I had a look today and all the wiring and mounting bracket are there for a stock trunk cd player. I would like to add an aftermarket with mp3 but have a few questions.
1) is there an after market cd that accepts class 2 signal?
2) would an after market work with its own remote?
3) is there a difference in stock head units that allow the rear cd player?
Also I located the amplifier (U80) behind the rear passenger back. No class 2 here in the wiring
That is really surprising.
When I was first looking by my SSEi back in 2000, there was an identical one that came it before my factory order was ready. They tried to sell it to me but it didn't have the 12 Disc trunk changer. They were more than willing to install one but couldn't because it didn't come with the bracket or wiring harness connection.
So I had to wait two more months for my SSEi to arrive.
There is no difference in stock head units.
Sorry I can't help with your questions.
What is a Class 2 connection???
