Hi all, has anyone else had any issues with the navigation on the Navi650. When driving along it seems to lag behind and follow the wrong roads as if it's lost GPS. It can be fine for miles but then as soon as you get into a town etc. It will completely get thrown off course. Will try a reset by taking a battery terminal off this week.

Has anyone else experienced this or similar before?

Not really a biggie for me as I don't rely on the maps, it's just a handy feature to have and would be nice
