Hi all,

I swapped out the touch screen on my 06 250 with ML NAV, And now Bluetooth/phone options have all disappeared from the menus. I've checked all connectors and can't see anything out of place. Any ideas what's gone wrong?

Thanks !

 

hmm that's unique, did you check all the wiring?

 

I removed the unit today, unplugged all the connectors and reconnected them, looked for any connectors I may have switched in error. It really is strange, I've searched and can't seem to find anyone else with the same issue. The rest of the unit is working fine which also makes me think it probably isn't a switched connector.

 

is he new headunit from the same MY?

 

Check the connector inside the unit. The small module on the side of the screen, You may have it disconnect

 

Yeah it is, I didn't swap out the whole unit, just the display,i also used the service menu today, BT firmware showing all blank .

 

I think this may be it. I'm going to pull the unit out over, the weekend and have a look!
