Not sure but has anybody else had an issue with an iphone 3G and the CTS. Mine worked great and now will still ring through the car, but will only let me speak through the phone or speakerphone. The phone is paired... etc.
I reset the iphone, still it sees the CTS fine, pairs easy but wont work.
I tried another iphone and it works, which pretty much isolates the phone but i figured I would just put this out there.
