My tablet is mounted on a KTM 1290 SAR, for size comparison. The android version is 12, I’m not overly tech savvy but it seems to work fine.
As far as visibility goes I have had no issues so far, it appears to be as good as the Garmin and the bikes own screen.
I may swap the mount location to where the Garmin is, as it is distracting looking down to where it is mounted at the moment.
The next decision is whether to bite the bullet and purchase the Adventure controller.
I will give the magnetic connectors a go and maybe use some silicone grease at the port, I use one to power my Sena 10c and it works well.
