@M-Schrijver which Android Auto panel are you using?
I've previously used MRA Nav Next on the infotainment system in my 2017 VW Tiguan, this works well, scale is good.
My only real complaint with my newly purchased panel (the Evkey L200) for my motorcycle is that of screen scaling. This is, I feel, is entirely down to the implementation/configuration of Android Auto on the panel. CarPlay seems to work well in this regard. It's not really an issue with MRA other than the options available to the user in terms of the zoom settings being limited in scope.
In essence the problem is something that the manufacturer of my panel needs to address, I'm really asking for comparison with other models here. However, it's has deepened my understanding of Nav Next and the limited options, in this case, within the configuration menus. Thank you all for your input in this regard.
Unless I can get a response for the manufacturer early this week the panel will be returned for a refund. A warning on buying new tech from the likes of AliExpress...
