Z10 in car: a horrible experience?

Hi everybody,

I have my Z10 for three weeks now and I love the device with one exception: on the road. I cannot answer calls using the controls on my steering wheel and my contacts aren't imported to my car. Also when I connect the device using the USB cable I can't play music, but I guess that's a iPhone only deal most of the time.

Any tips? The car is an Opel Astra (or Vauxhall Astra for the UK people here). Any suggestion to replace my car will be ignored. Unless sponsorships present itself of course, go Maserati!
