Strange, I see that Sharan has CarNet, whereas my Alhambra doesn't (these are practically identical cars built in the same factory). Mine has a button for "preheating" on the dashboard + a small keychain remote control that has a surprisingly long range. I didn't even activate MirrorLink & AndroidAuto in it because it costs an extra 200€ or so #cheapbastard (honestly though, initially waze wasn't working with AndroidAuto, and by the time it started working I figured out I can just pin my phone to the dashboard and be done with it)
