Never had any problems before but I had some minor work done on my vehicle, got it back and suddenly my I-phone won't connect to bluetooth on my Z110BT radio. I tried re-registering my phone, it registers successfully but still won't connect. Anyone know how to fix this?

I ran into a similar problem with my phone. Go to the BT settings of your phone, delete the Pioneer. Then start all over.

I had to do it like three times before it would work every time.
