Have any of you guys got hands free kits fitted.
I am due to get one soon and when I spoke to our fitters they said I would need a separate speaker as they could not link in to teh audio system.
This is probably similar to threads I have read about fiited subs etc.
Something called canbus I believe which send info as well as audio down the wires.
Anyone had anything fitted by Chrysler. I have looked at bluetooth kits like Parrot but I could do with a cradle for charging the phone.
Any thoughts.
