In the continuing 'my nav won't work' saga, a bit of a favour. Is there anyone with an e53 anywhere local to north dorset (or Salisbury) who might let me try a 'swap-in, swap-out' with a working mk4 dvd unit to assess whether mine is knackered or not. At least then I know if it's worth the £200 for a re-conned one. It's a lot to ask I know, but it's a ten-minute job (with no real mechanicals -just two clip-in leads and an aerial to swap over) and I can fund a beer or two.

Yours in hope,
DBVN
