so I have tried moving the cell phone around, once in a while, it sounds fine, most of the time is is totally crappy sounding and garbled up , any way to fix this or replace the blue tooth. not looking to take to a dealer and get a $1000 charge fo this either.
thank you

check under the front passenger seat to see if your bluetooth adapter is hiding under there (not sure where it is on your model- it may be in the dash). usually garbling etc is either the device or wiring is bad (ie bad ground wire) so I'd start by inspecting cleaning the connector. if you find the unit is bad, you may be able to find a used unit to swap in from eBay etc. There are also after market adaptors from Grom etc that plug into the head unit. Check out Crutchfields.com com as a research source.
