Sat nav screen repair - anyone around East Anglia

[Fab]

I've picked up the dead RH side problem on my Discover Media system, and have been looking around for a repair. As I'm up in Norwich I was hoping for something nearby, or not too far away - day trip perhaps. I'm not confident about removing the device and putting it in the post.

I had a scan of all the discussions about screen repairs and haven't been able to find anything closer than SatNav Systems in Surbiton. Tab-Tec in Northampton is on holiday until June.
