RR Satnav Q???

[triple7]

Had a flat battery, AA disconnected battery terminals, so all power lost to electronics. Everything seems ok apart from the Satnav. The map image does not now fit the full screen width, looks squashed. I've read the huge manual, but to adjust the resolution I need to access the OCD menu functions but cannot seem to beable to do this?

Any thoughts/ideas??

Thanx.
