My TOMTOM XXL indicates: Device Memory 1958.5MB
Installed Items 1649.3MB
New Items: 309.0MB
You need to free space 673.7MB
Some items do not fit on your device
There is NO map installed.

How I can free space?
How I can install an OLD map. (I do not have a copy)
Better: How I can clean all the memory and start from scratch if possible?

Thank you,
