SAT NAV radio phone etc I think but not the message centre, I'd have to check to be sure as I only have the module, I have also repaired the TV module in the past which also killed everything.

i guess the only way iam going to find the module at fault by swapping them in turn for known good ones?

Yes, but more than one could be faulty so really you need a set

There must be places in the UK that can test and repair, there is certainly one in Holland that I may be able to report on in the New Year.

its looking more like a main stealer job then as they should have access to a set of new modules, unless i can find a willing donor vehicle owner

You jest

A main stealer will just bill you £2k to replace the lot.

They don't keep spares on the shelf, too expensive.

ha ok, donor vehicle itl have to be then

More often then not the unit that goes tits most often is the DSP Amp unit....which is a bitch cos it is the more expensive one!!

Already answered that, you should still have audio with the CD?DVD NAV unit removed as far as I know.

I use contact cleaner and a special glass fibre brush, you need to be very careful with the small pins, they are fragile. Tissue soaked in cleaner and a very small screwdriver can be used to clean around and between the pins which is very important.

i think i can manage that , maybe a wooden touthpick soaked in contact cleaner would work well?

If you cut the pointy end off and add tissue it will do the job, not as good as a small flat blade screwdriver though.

Dont forget - even if you remove the Sat Nav unit....if the DSP is fecked you still won't get a bean from the ICE

paulvasey · Dec 27, 2012

yer, i now have nav and dsp removed and cleaned, tommorrow ill do the radio and tuner

paulvasey · Dec 27, 2012

paulvasey · Dec 28, 2012

Probably, as I said all along from bitter experience, corroded connectors corrupting signals.

i guess ill know when i put it back together,there was some depoisits at the base of the bm54 unit but the pins were in good order, could have been shorting i guess?
