Electrical gremlins

[Globetrotter39]

I think this has been asked before but I can't find a sensible answer, 2004XC90 T6. Radio, satnav and reversing sensors all packed up together, Any ideas folks?

I would start by looking at the fuses as I wouldn't be at all surprised if all 3 were on the same one as they are linked.

All of those systems are on the same fuses / audio system

So look for the common components:
Fuses (if no power to any of the three)
Amplifier (if not sound from any of the three)

VIDA will help enormously here as without VIDA you are hunting in the dark

I have similar problems with my 2005 T6, every now & again the gremlins get in and cause mischief with these systems.
Random speakers will stop working (although drivers door speaker now off permanently)
Radio will randomly loose station settings
DVD won't read disc's - even though they were playing fine 5 min previously
DVD screen in driver seat works occassionally
parking sensors work/don't work, sometimes get park assist warning, then sometimes not (Wife's excuse for bashing the lower boot lid on post - no beeps?)

Sometimes its a case of using the IT fix all which is to just turn the ignition off and back on again and sometimes all is well but sometimes it takes a few goes.

Vida does throw up the occasional fault, i.e. sensor error but goes away when further investigation testing etc.

I will continue to investigate and have been systematically cleaning connections and checking wiring etc. hopefully one day I will get the pesky critter hiding in the loom and deal with it appropriately/humanely!
