Convert Sensus system to icup?

[IMAY2023]

You don't need to change anything, There are retrofit devices for that.

Yes, but you are missing the climate control settings and such. You always need to switch back. The native one in the icup always have the climate control/seat/steeringwheel heating on the bottom. Much better.

I did not know that, you are right though I wouldn't add that. I have regular Sensus which I like but I agree that Android auto or apple car could be better with full screen option. 
On the other hand, new models come with android using only google maps which I hate because it forces to have constant internet connection either with onboard modem or hotspot from a phone. In Europe, it may not be a problem but in US there are so many urban places with no cellular network.
