Hi all, So my sat nav has conked and I’m wondering if it’s the disc or the DVD unit at fault. It happened mid journey and I got the error message attached in the pic. I’ve cleaned the disc (which is the original from 2007), which was dirty but it’s not made any difference. It does have a couple of very fine scratches on it but these haven’t stopped it working without any issue for my 5 years of ownership. I’m thinking it’s probably the unit, but before I blow £170 in repair charges (BBA reman quote) , does anyone live in the Cheshire area who has a f/l 7th Generation with sat nav who wouldn’t mind me trying my disc in their car? I get this is a big ask but thought I’d put it out there anyway... HH have quoted @£200 for a new disc, I’m unsure of quality of discs being offered on eBay.. Thanks..
