ok now I have to jump on the band wagon here and get my truck upgraded to stream music and phone calls...one problem though, I have no idea what I need. Doing some quick research I have to think that the MEX-BT2600 or MEX-BT2700 are the units within my price range, but what else do I need besides the unit. With bluetooth built in, the only thing I should need would be a wiring harness for my specific truck correct? or do I need any adapters?
