Another plea for KISS
Having had a few cars with their own "approach" to in car software, I really, really, really, really don't want any more.
All I want is a rock-solid bluetooth connection, so I can use MY phone, MY player, MY satnav.
Everything else is just a waste of mine (and the manufacturers) time.
The only thing the car should provide is a decent (10"+) touchscreen that my Android/iPhone can cast to, for ease of use.
