pac and peripheral both use the same piece when it comes to the tr7. i will check and see whats going on with kenwood. any honest installer will tell you that kenwood is not as good as pioneer or alpine.ok this is what i got to date.
Alpine INE-Z928HD The place said that they had one just installed it into a Raptor, they said the Sync did not work or user didn't care. They said to shop around for a install kit as the Alpine perfect fit was too much money.
Also got the the PAC unit for the Sync system and the unit that bypasses so you can operate the nav while driving, I think it is the same as the TR7.They went and picked the unit up and had it to me the next day, great service.
When I asked other places for availability of the Alpine they all suggested the Kenwood unit also.
Got an install kit bezel and mounting bracket, only problem had to get black and was cheap so I can experiment with that to see how it fits, not sure I can get the correct silver one to match my dash.
The only thing I am not sure about is do I need something for the steering wheel controls. I don't think so at the moment.
The install is another thing going to attempt next week looks like it's going to be fun and not in a good way..
for steering wheel controls you need the "swi-jack" and need to program it to your vehicles steering wheel buttons. i just did one today with the z920.
i just recently disassembled a raptor, let me know if you need help.
