Radio Wiring Help
 

just drove the new s home from south carolina last night. i have the bose "premium" sound package (no rear speakers with this?) and a sony aftermarket head unit with xm changer built in. a couple of questions while waiting for delivery of my bentley:
1. the "bus in" input of the unit is occupied--does anyone know if this is for an xm control box of some sort? i'd like to plug my mp3 player into that slot...
2. i got no AM reception, and fairly crappy FM reception. prior experience has told me that this is from a blown/not powered antenna amp. does this car have an amp?
3. there's a lonely, unconnected blue/brown wire from the car--anyone know what this is? illumination control, antenna amp power lead maybe?

thanks!
'02 Boxster S Silver/Black

Where is the Blue/Brn wire located - behind the h/u? If so, I beleive this is for the speedometer hook up on an '02 for the speed dependent volume signal. Your new h/u may not have this. Picture of and place will help.

As for the reception, since both are bad, sounds like your antenna lead may not be hooked up (or correctly) but yes there is an antenna amplifier. I think the wire colors are white for the antenna and orange for the power lead to it.

Hope this helps!

yeah, that's kinda what i figured as far as the amp goes.. i already put the radio back in, but tat wire's behind the h/u with a female spade connector on the end. would anyone be willing to scan me a wiring diagram?
