ok hoping all will be ok as I'm still in the middle,
1> I backup up manually my tomtom to a folder on my pc
2> I backup up using home as well to a separate folder on my pc
3> went to do an upgrade and I got a message similar to
"insert a memory card for your new items, they don't currently fit on your navigation device"
So I didn't have an SD card so I wiped my go630
then went through and started the download quite a while later it errord
"saying f:/north_america_2gb#td_canada_trust_green_machines.ov2"
does not exist. so it exited, then when resetting my tt it kept asking for a SD card
went back to home and said that the map hadnt completed, so it did its stuff
now looks like the home is adding more files, go630 and now car and motor navigation
I'm just going through it now and hope I had got problems
