[Review] iGPSPORT "BiNavi", a higher-end model with enhanced navigation functions compared to the iGS800

I bought iGPSPORT's new product ``BiNavi'', which was released in March 2025, so I will review it.

The weak navigation function of the previous model, iGS800, has been improved, and the runtime, which was excessive for general users, has been reduced to 35 hours. That's about the extent of the difference from iGS800, but it's a bargain model with a price that is 26% cheaper.

■ Overall rating

It deviates from the previous naming rule of iGSxxx, so it may seem like a new product, but it is actually a higher-end model of the iGS800. More details will be provided later.

■ Purchasing motivation

The top model of iGPSPORT's cycle computer to date is the iGS800. It is a highly complete product in terms of both hardware and software, but its only weakness is the navigation system. The built-in map was particularly difficult to read, but I immediately purchased it because they had improved the navigation system.

It was announced on 2025/03/21 and was available for purchase on Amazon on 3/22. I was skeptical when I ordered it because it said that if you order in the morning, it will arrive that evening, and it really did arrive on the evening of 3/22.

By the way, on March 21st, other light models were also announced, including the "VS1800S," an improved version of the VS1800, and the "SR mini," a radar tail light.

Spec comparison with iGS800

Next, we will compare it with the iGS800, which is a question we often get asked about. The basic specs are the same except for the runtime. Other differences are as follows, and you can see that there are many areas where the specs have been improved.

As you can see, the specs are very similar, but on the iGPSPORT website, BiNavi is listed as a "Navigation Cycle Computer", while the iGS800 and others are listed as "Smart GPS Cycle Computers", which are products in different categories.

I suspect that iGPSPORT wants to sell it as a product in a different genre to avoid competing with the iGS800. However, the more I use it, the more I can only see that BiNavi is a higher-end model of the iGS800.

The iGS800 does have a longer battery runtime, so to make things more complicated, it can't be said to be a superior model in general.

However, the only major feature that has been downgraded is the runtime. I think this is a typical iGPSPORT product strategy of "releasing a new model with improved performance from existing models while lowering the price."

I would like to emphasize that this is not a product that is generally considered to be "specialized for navigation, but with simplified cycle computer functions and a lower price." It is a model that is "26% cheaper than the iGS800, but with enhanced functions."

Unpacking ceremony (package and included items)

Here is an introduction to the package and what is included. The package is here. It is the same size package as the iGS800. Unlike the iGS800, which was advertised by Froome, the navigation screen is emphasized, which shows the character of the product.

The product features are listed on the back of the package.

When you remove the sleeve, you'll see the main body in a white package.

The following items are included: From the left, a silicone case and LCD protective sheet, a USB Type-C cable, a Garmin compatible mount, and a Quick Master Manual. Many iGPSPORT cycle computers, including the BiNavi, come with a silicone case and LCD protective sheet as standard, which is a very positive point.

Actual weight

The actual weight was 103g, compared to the nominal weight of 103g. As mentioned above, the actual weight of the iGS800 is 107g.
* LCD protective film is not attached.

exterior

The size of the device is almost the same, so the appearance is indistinguishable from the iGS800, but the BiNavi is 2mm thinner to compensate for the reduced battery capacity. The bezel is as narrow as the iGS800, which is an excellent point.

The back side. The mount was aluminum on the iGS800, but on the BiNavi it has gone back to resin.

Power button on the left side.

On the right side there is a decision button and up and down selection buttons.

On the bottom are the lap button and the ride start button. The charging port is USB Type-C.

Basic Functions

Although BiNavi emphasizes the enhanced navigation function, it is also a highly functional cycle computer with the same functions as the iGS800. All the new functions realized in the iGS800 are implemented. The main functions are introduced below.

Dual-band GPS

The GPS (or GNSS, to be precise) now supports dual-band radio reception, improving accuracy. Garmin has supported this feature since the Edge 1040.

Automatic reroute function

When performing route navigation, if you stray from the route, this function will display a route back to the original route.

Widget-driven interface

The top screen features a vertical layout of widgets for each menu, called "color cards" (in the image, BiNavi is on the right).

BiNavi has evolved even further, and now offers an interface with smartphone-style icons.

iClimb

This is what Garmin calls ClimbPro, which has become quite common now. If you display a route you created in advance, it will detect the climbs included in the route and display your profile and progress.

The conditions for detecting a climb are a gradient of 3% or more and a distance of 500m or more. The iClimb function has been improved compared to the iGS800, and more details will be provided later.

Automatic lap function based on registered positions

It supports the function "automatically cut the lap when passing a registered position" which is in demand in circuit enduros, etc. When using this function, make sure to set the GPS accuracy to maximum.

Status display function

It now suggests "exercise status," "fitness level," and "recovery status" according to the training situation. This was a notable new feature on the iGS800, but it can also be used on BiNavi.

Touch Panel

The touch panel implemented in the iGS800. BiNavi is also compatible. At a time when the Edge1040 cost 100,000 yen, the iGS800 was priced at around 50,000 yen with a smooth-working 3.5-inch large touch panel. I was surprised when it was released, but it has become commonplace now. BiNavi has also dropped in price to 40,000 yen.

Increase in number of displayed items

Like the iGS800, this also supports displaying up to 12 items. I have the Di2 shift position displayed on the top, taking up two frames, so I have 11 items, but it can support up to 12 items.

About Navigation

Now, let's take a look at the essential navigation features. As mentioned earlier, there are no problems with GPS accuracy, as it supports dual bands. Here, we will mainly introduce the new features implemented in BiNavi.

Added high contrast mode

Previously, it was difficult to distinguish roads on maps, but a new mode called "Colorful" has been added, making it easier to see. The right is BiNavi, and the left is iGS800. Major roads are highlighted, and parks and other areas are also displayed.

This is the state of the Teimune 200 that I ran the other day. The bottom is BiNavi, navigation is running. The top is iGS800, not navigating. You can see that the amount of information on the map is quite different.

Here are three cars lined up from the left: iGS800, BiNavi, and Edge1040. BiNavi is also doing its best, but the map on Edge1040 is clearer and easier to see. You need to minimize the time you spend looking at the navigation system while driving, but I think Edge1040 is more intuitive.

Improve route analysis accuracy

If the setting to display guidance during navigation is turned on, left and right turn arrows will appear, but improved analysis accuracy now allows the system to identify sharp and obtuse corner angles.

Here is a comparison of the displays of BiNavi and iGS800 when approaching the same intersection. BiNavi shows that the upcoming intersection is a sharp right turn. This is useful for identifying intersections where you should turn.

Here is the display on the iGS800 in the same place. You can see that it is turning right. It is a common display.

By the way, this is what happens at an obtuse angle intersection.

Increased number of items displayed simultaneously with the map

The number of items that can be displayed simultaneously with the map has been increased from two on the iGS800 to a maximum of six.

For canoeing and hill climbing, you need a navigation system in addition to a cycle computer, but you want to have only one device to reduce weight, and I think this specification meets that need. I'm sure there will be people who like this.

Simultaneous display of iClimb and map

This is a similar addition to the increase in the number of items displayed simultaneously with the map mentioned earlier, but BiNavi now allows you to split the screen into two halves, top and bottom, and display navigation and iClimb simultaneously.

On the iGS800, the screen is dedicated to iClimb like this (the top is the iGS800), so if there was a possibility of turning right or left while climbing, you had to give up on iClimb and display the navigation screen.

The entire route is visible

The performance of route analysis has been improved compared to the iGS800, and the entire route is now displayed. For example, here is BiNavi. The return route passes nearby, but it is displayed clearly.

This is the display on the iGS800 at the same location. I'm navigating the same route, but the return route is not displayed at all.

However, in order to reduce the time required for analysis, BiNavi does not display the entire route in detail. For example, this is the route of the Teinomine 200 that I ran the other day, but in the latter half of the route, Matsugo Pass, the points have been thinned out and it is a straight route.

The details are displayed when you actually arrive at the site, so there were no particular issues at this pass.

I wrote "at this pass" because there was an inconvenience in another situation. For example, this is the same route of Sadamine 200. For about 30km from the start, the route is the same on both the outbound and return trips, but for some reason, a different route is displayed on the screen.

As mentioned above, this is because the latter half of the route is displayed in a linear fashion with fewer points removed. However, I was a little confused because a different route was displayed for the return trip, even though the same route was supposed to be taken.

For now, you just need to follow the guide arrows, but some people may be confused if they are not familiar with this specification. How many kilometers ahead is the detailed display? However, it was displayed in detail up to about 25 km ahead.

Climb Preview

This is a function that allows you to check the climbs recognized by iClimb in advance when loading a course and running navigation. This is not a new function, but a function that has been available since the iGS800.

Offline Route

The "Offline Route" widget on the top screen allows you to draw a route to a specific point saved in the app.

To use this function, first connect BiNavi to the app and enter the settings screen. The menu you will use is "Location Point Management."

Specify any point on this screen, give it a name, and save it. Then, you can call up the saved point from the "offline route" and navigate immediately to it.

Next to "Location Point Management" on the previous app screen, there was a menu called "One-click Navigation," which has the same function. In the product description, it is called "One-tap Navi."

This involves drawing a route to a point that has been saved in advance on the app, and then transferring the route to the device (implemented on the iGS800).

Differences from iGS800

I will introduce the differences between the iGS800 and the iGS800 other than the navigation system. In all images, the BiNavi is on the right. First of all, the function to connect to wifi and upload logs has been removed.

A status bar has been added that is always visible at the top of the screen.

This is the status bar (BiNavi is on the right in the image). The time, remaining battery level (in %), and GPS signal strength are always displayed. Until now, one frame was used for the current time, but now it can be used for other items.

It is now possible to communicate with deep body thermometers, which are popular these days.

The only item that can be displayed on the cycle computer screen (page field) is body temperature.

Looking at the website of the major product "CORE", the brands of compatible devices are listed as GARMIN, wahoo, and Suunto, but there is no iGPSPORT... In recent summers, if you don't measure your core body temperature, you can easily get heatstroke, so I was thinking of buying "CORE" too. Once I buy it, I'll try to see if it's possible to connect.

There is also a difference in the display of the color cards. In this case, the iGS800 shows more detailed information.

Also, the initial course analysis speed when running navigation was definitely faster with BiNavi. When we tried to run the same course at the same time, BiNavi was displayed first (the image below is BiNavi).

By the way, the iGPSPORT website says that "a 1,000km course can be planned in 1 second," but that doesn't mean the initial analysis like this time. For a 1,000km course, it says that "the initial route analysis takes 15 seconds," so it takes a fair amount of time.

Other new features from BiNavi

"Continue Later" feature

When you use this function while recording a ride, the ride log is temporarily saved, the log will not be erased even if the power is turned off, and logging will automatically resume after the power is turned back on.

Here's the flow. First, start the ride normally.

Use the function button on the top right to call up the menu and select "Continue Later." Tap to return to the top screen.

I was worried because there was no message saying "Saved temporarily" or anything like that, but I turned off the power anyway. It seems to be saved in the memory.

When you turn it back on, the following message will automatically appear. I forgot to take a picture of the cycle computer screen, but it resumed exactly from the previous state.

You may be wondering "What is the difference between this and the sleep function?", but the sleep function may be activated unexpectedly. Turning off the power when taking a nap is a sure way to save power, so this seems useful for distances of 600km or more.

Group riding

This function allows you to display the location of your friends on the map screen. Details are unknown as this function has not been implemented at the time of writing, but the iGPSPORT website states that it will be released in April 2025. It is likely that this function can only be used by users who are also using BiNavi.

This is a feature that Garmin also implements in the Edge 1050.

About runtime

The important thing is the runtime. This time, I used it in a 200km brevet called "Teiho 200".

The start time was 7:00, so navigation started at 7:00. The battery level at the start was 100%. I navigated the 200km course and drove 200km with three sensors connected.

We reached the finish line about 11 hours later (18:00), completed the finish procedures, chatted, and then walked to the Times Center 4km away where our car was parked, where we finally turned off the power.

As a result, the runtime was 39% at 11:50. If the runtime was about 40% at 12 hours, it would be about 20% at 6 hours. Under these conditions, the runtime would be 30 hours.

The official runtime is said to be "up to 35 hours," so with the navigation system running, sensors connected, and the backlight on, it can be said that the estimated 30 hours is roughly in line with the official runtime.

■ Summary

This is a navigation cycle computer from iGPSPORT, released in March 2025.

There are some shops that think that this is a cycle computer specialized for navigation, but in reality it is a high-end model with improved cycle computer and navigation functions of the iGS800. Apart from the short runtime, this is the top model at the moment.

And yet, the price is less than 40,000 yen, making it a very good deal. The runtime of the iGS800 is about 50 hours, so if you don't need that, I think the BiNavi is the only choice.

Personally, I don't think it's as good as the Edge 1040/1050 (but that can't be helped, given the different prices), but what I like about it is that the maps are much easier to read, the UI has been improved, and the body is 2mm thinner.

As usual, iGPSPORT is a contrarian product development of G, surpassing the previous model in terms of functionality and lowering the price. As a user, I'm happy, but I'm worried about whether it's okay to not raise the product price more.

The cycle computer function is currently near completion, so if they could just make the map easier to read, even if it meant spending the extra money (I'd be happy to pay 20,000-30,000 yen), I think it would be quite complete.

If you are wondering, "Is BiNavi specialized for navigation, but I don't want to have cycle computer functions that are inferior to the iGS800," then you don't have to worry about that, so I recommend you buy BiNavi.
