Mk4 Nav - No power unless I hold Eject
 
Hi all,

I recently upgraded my Mk3 nav to a Mk4 unit. All worked great for 3 months, then the other day it just went blank on me, and the next day the TV module took over.

Looking at the nav unit, I see the power light is off, but a small light flickers to the left-edge of the DVD slot. If I hold my finger on the Eject button the unit powers up (the red power light comes on) and the nav system displays on the dash-screen, but as soon as I remove my finger it dies and the screen goes blank.

Is this indicative of a common problem? I've taken the unit apart and can see no obvious issues with broken soldering, etc, but I'm by no means an electronics expert.

Any tips / advice welcome.

Many thanks!

Edit: I have exactly the symptoms described in this thread, but there's no ultimate solution there, hence posting.

Hello.

Managed to solve the problem of your MKIV ??

Holy thread resurrection, Batman. Yes, I replaced it with another unit and sold the faulty one for spares or repair. I've since sold the car.

OK, thanks.
