1) What swap did you make? MK3 to MK4?

2) Did you adjust the connections at the TV monitor (white & blue pugs) or only adjust the nav (blue and wine plugs)

3) BMW logo comes with later versions of the Operating System

4) Did you remove the battery -ve terminal for 30 minutes.

Yes first remove the battery -VE, and wait 30 minutes, then reconnect.

After this, if TV is working, set the clock. I think you may never get back your missing clock logo, sorry.

Temporarily swap back in old MK3.

Old mk3 is kaput....no Power LED!

Unplug new MK3. The TV should take over graphics generation.

No LCD display graphics = Kaput TV tuner. Sorry.

For me, TV is not really a big deal. They are switching to digital TV soon anyways.

Edit: you could check the TV tuner a little more. You can use Navcoder and a Resler interface to check the TV it there, you can check for bad wiring in the antenna or the connectors, you can check for voltages on the cables, you can take off the battery and the nav all night and see if the TV tuner comes back!
