sattelites. Afterwards it has an offset which does not get eliminated until
turned off.

I consider the problem with the mkgmap generated maps and searching

4 direction buttons and an okay - and entering text works like a charm.
Its a UI problem and with Garmin the Software Developers are free
to design the UI ...
