Ok so I swapped the monitor, so for anybody wanting to know, it was a simple straight swap, everything just worked exactly as it was before, radio settings, Nav settings, everything.

I am having an issue with the CD player version that I just bought on ebay however. This is a little off topic I know, but I hoped somebody might have some experience of this...

I swapped the cassette monitor for the CD version as I said, but although the unit appears to load and play a CD OK, it is doing wiered things. The best I can do to narrow it down is that if I use the < or > buttons to select a track, that track will stop abrubptly after around 10 secondss, and there is just silence as if the unit has frozen until I select another mode, but if I use the steering wheel controls to skip it doesnt.

I cant really explain this, but it does it most times i use the controls on the head unit.

Anybody else experienced this ?

Thanks
