Hi. I've upgraded to v29 today and it all works fine. I'm still running 3-1/63 so I guess I haven't broken anything.
I can't get new maps to load though. The car came with a blue cd 'Digital Road Map - Britain and Ireland 2004/1' and I've bought 'Road Map Europe PROFESSIONAL 06-2 (DVD Part No T1000-10415). I DO have option 609 for professional navigation.
I changed the CD over, but the computer just spat it out again!
So I thought I'd try the Road Map Europe HIGH 06-2 which also won't run.
What am I doing wrong?
