Anyone out there know how to solve this one. ?...
My GPS 90 now displays the message "Read Only Memory has failed".
- but there appears to be absolutely nothing missing performance-wise. If it's
doing a checksum, I suppose there could be a bit changed in the database
somewhere, which it would be hard to detect or rectify. It so happens that
this only appeared after I had been trying to input some routes which I had
changed from a different format, probably incorrectly, and it rejected them.
