No, you can swap the unit without fear of upsetting anything.

It doesn't seem to be rust in the spare wheel well. Just 19 years of accumulated dirt !!

I have just removed the 'new' SatNav unit and found that the pink plug was not attached. I re-attached it and moved the locking arm into position and put the unit back.

Hooray, I thought. Problem solved.

But no. Still no display.

Any other thoughts anyone ??

Was that your mistake Andrew when you fitted the replacement unit or could it have been the actions of Mr. Previous Owner?

The person from the breaker's yard had the forked prongs to remove the old one and he attached the new one.

I have asked the breaker whether the Alpine head is available since there is not a problem with radio codes. The Satnav was £35 so if available, hope the head will be similarly priced.

Thanks everyone.

The head unit in the 75 he is breaking is not an Alpine.

Anyone have one going spare ???

Hi Andrew,

This is a very unusual fault which I don't believe we've come across before.
Would you like to try my video module in your car since that's the unit responsible for the screen display? [Correction: it's the navigation computer] I'm just down the road from you. Send me a PM if you're interested.

Simon

Andrew brought his tourer over this afternoon. The fault wasn't with the head unit's LCD screen. The second-hand navigation disc drive/computer was the culprit. The disc inside (which Andrew suspects is a copy of a BMW disc, it wasn't Navteq or VDO Dayton) didn't work either.

I am pleased to have been able to help him with an accurate diagnosis at zero cost.
