Thanks for your suggestions;
Have tried 1. hard reset and erased all user data with same result.
Will try 2. as you mentioned, but even when tried with the internal map deselected in Maps-Info, the boot time was the same.
How do I defrag files in the internal "mass storage"? Can I just hook it up on windows PC and run defrag (or defraggler) on it?
Is there any way I can reset all internal files, databases, and start from a clean scratch again, like re-installing an OS on a computer? The Hard reset does neet seem to purge all the rubbish, it would seem...???
Appreciate all help...
