I gave it 4 stars because you cannot do this with any other device but it could be a lot better.
Pro:
- it works. I have a BMW R1250 R from 2021 and it worked after the software update(see Con's :P).Before the software update it was seeing data like gear I am in or engine RPM for my case. It was not seen from the BMW TFT though as navigation
- since the control happens through wonder wheel the ergonomics is better than any other remote :)
- i chose this over the CAN module not only because i did not have the alarm/tpms modules on the motorcycle but the control is separate from the TFT. You can switch between the TFT and the Aio 5 as you would with the original equipment
Con:
- Doing the update for the motorcycle was a bit of an adventure. Make sure you have this already inserted in the motorcycle nav port. On the newer versions of ISTA you can only update everything or nothing and if it does not see anything connected there it will not update the navigation. The dealership was helpful on that regard for my case.
- I had a USB-A charger on the navigation port as it supports up to 10A. This ocupies the port and does not offer anything. It could have itself a USB port or at least a port for the Aio 5. As is i made a split for the cables and cut the cable for the Aio 5 the LIN module and the USB charger but it could have been alot better with LIN already having these ports
- the control does not really take commands as it should. Sometimes(not often) it goes back instead of forward for some reason. The BMW wheel works perfect with the TFT btw.
- this one is more for android itself it think(not sure). It is not intuitive to use the menu on the android with the wheel. I am not sure because it seems a bit better on my car that has the iDrive wheel but for this one it is sometimes frustrating to get out and in of certain menu's. Like going from the zoom to the bottom play/pause works but going back to the zoom is hard. Will have to test more to see for this issue.
- There seem to be no firmware update possible and that is a bit scary(future BMW updates could render this useless).
- as expensive as it is again i think it should have had the ports for the Aio 5 and USB in it.

I can’t say if the device is good or not because unfortunately it did not work on my specific bike. Three star because customer support was really great in finding a solution to this issue.

Ich habe mir vor einiger Zeit (kurz vor Veröffentichung des CGRC LIN) das CGRC CAN für BMW gekauft und war schon sehr begeistert über die Funktionalität. Leider wurde mir zum damaligen Zeitpunkt nicht angezeigt, dass es ein neues Produkt (CGRC LIN) geben wird, sonst hätte ich mir das CGRC CAN nicht gekauft. Das vielleicht als Kritikpunkt. Ansonsten bin ich mit dem CGRC LIN absolut zufrieden. Die Bedienung funktioniert nun so, wie ich mir das vorstellen. Es gibt zwar hin und wieder Verzögerungen bei der Auswahl was ich allerdings auf die Auswahl über das Drehrad zurückführe. Die Informationen, die mit dem CGRC LIN bereitgestellt werden, würde mich Grundsätzlich befähigen ohne BMW Display zu fahren. Ich bin sehr zufrieden und kann diese Erweiterung nur jedem empfehlen.

As with everything Chigee it is well made technically superior to anything else available in the UK and easy to use.

The CGLIN is fantastic. I have the AIO-5 LITE and it works very well. Installation was 10 seconds and now wonder wheel works much better and CHIGEE AIO have access to data on the bike. It has all functionalities of the AIO-5 PLAY for BMW. Very happy with it
