my 2000 xjr Alpine premium stereo unit has been acting up recent. only the main display led will lid up but all buttons light won't .

also the volume control on the steering wheel also won't work any more?


any ideas?thanks in advance

 

any body?

 

Sounds like it's broken?
Sorry, can't say I've heard of anything like this before. Best thing I can suggest is ditch it and buy a second hand unit

 

Does the radio work at all or is the problem just the buttons not being lighting up and the volume control on the steering wheel not working??

Are you getting any sound coming from the speakers?

You need to give us more information for us to help you.

very thing else works, for addition information.

I changed my entire shifter assembly as I post on another thread and it happened right after that, I wonder it is related.

 

Likely jarred some wiring/connection loose when dealing w/ shifter.

 

I think King Charles is right, something was bumped in your wiring while you worked on the gear selector. I just studied the X308 schematics and think there is a clue.

Is it possible that a connector on the back of the radio was partially pulled out of the back of the radio? The radio lighting and steering wheel controls all connect to the head unit at a white 20-way connector on the back of the head unit (IC10 on the schematics).

The radio ground is via a braided cable to a ground stud just forward of the gear selector mechanism on the transmission tunnel, but if everything on the radio is working other than the lighting and steering wheel volume control, the ground is probably OK.

I don't think you'll need this, but since I made these notes I'll include them:

The power for the radio "dimmer override" is on a Red wire with a Green tracer; the radio illumination supply is on a Red wire with Pink tracer. These wires run to connector IC1, a white 14-way multi-lock connector at the "LH Heelboard" (maybe the left hand footwell finisher trim or scuttle?); then to connector CA19, a yellow 20-way multi-lock connector at the "Left A-post behind finisher."

The steering wheel radio control switches connect to the radio via a Purple/Yellow wire; and the switches connect to logic ground via a Black/Orange then Black Pink wire to Logic Ground FC17R on the EMS bulkhead ground stud.

The common point for those circuits is the IC10 connector on the back of the radio head unit. Hope this is helpful! Please keep us informed.

Cheers,

Yeah that information would've been a lot more useful in the first post. Sounds like you might have caught the harness on something and now the illumination wire is broken

 

thanks
