2006 Radio Wiring

[Mike Whyte]

Does anyone know if the wiring for the radio connections for a 2006 PT is different than a 2002-2005 PT. I have a RB1 Navigation radio that I know works and plugged it into a 2006 PT and it doesn't work. The plugs are the same so I'm guessing the wiring is different. The mounting is different but with the same plugs in back, I thought it would work. I checked to see if there was a ground issue and ran a temporary wire out to the battery negative but nothing changed. Ok, what am I missing besides my mind!!!!!!!!!

Well, I didn't get an answer here but someone called someone else and said that the 2006 has some cam bus so even though the plug is the same for the radio, it won't work. Just thought I'd post this in case anyone else could use the info.
