My PCM is switching itself on and off continuosly. Anyone else have the same problem? Then it will lose navigation and cd changer... making the whole unit useless.

Will be taking it back this week to check, but wanna grab some ideas to see if this is a common problem.

Please chime in.

 

take it back , may be a connection issue. Mine it wouldnt turn on at one point, it has something to do with the fiber optic connection...

 

I agree a bent fibre sounds most likely the cause, this should make the dealers head spin.

 

never heard of that before.

 

i had this happen but they gave me new PCM.

 

It's that curse again, the RING is back...
