Hi all, thanks for the add, need some advice please, l322 04 td6, radio problem, hat flat battery, put leads on and jump started, fired up 1st turn, no problem,but have lost audio no Amber power light on head unit,sat nav works but no sound all computer functions ok screen is all right checked fuses under cd changer all ok boot compartment is dry anyone got any further ideas please?

Don't know much about the old style head units but the newer 07MY on are run off a plastic fibre optic network. If one of the components goes down (mine had a drowned Bluetooth unit) then it kills the entire network.

If you do have the fibres then you can unplug them and look into the fibre to see if there is any light.

Note there'd be a pair, one is transmit and the other is receive so light may only come out of one. Ed

Won't be a MOST system.

Suggest do some fault finding, check all related fuses, dive into the left rear boot space and check and reseat all connections on the AV kit. Worth also a battery disconnect procedure. .

It's early 04 tried battery disconnect and fuses 8 and 48? Under cd changer just no power on light on head unit

Are there any more inline fuses or internals on amp?

No there aren't, have you followed the proper battery disconnection procedure, it's in the WIKI..

There's a 10A fuse in the top of the radio BM54 unit. Remove the large connector plug from the unit and it can be seen underneath. No reason a flat battery should cause it to blow but you never know.

My 2002 radio one day didn't work. I suffered for a month, and eventually, tried the battery disconnect procedure, and now it's working. But the cd is dead. I can live with that. Sort of scared to fiddle again, in case it's screws up.
