Does any one out there use these? I just recently purchased one..... a TOM TOM. I am having some issues with my own home address being located wrong on the gps. It's a mile off. The unit functions correctly, it's just my home address is off. I have contacted tom tom and waiting for a response. I also have updated the unit with latest firmware and maps. I was just wondering if any one else had such a problem and if there was a quick fix for it. It's is even wrong on Google earth. It's off just shy of a 1/4 mile or less. At least I can see my house when google earth marks the spot. before it had the same location as tomtom does now. So the logical conclusion is it's in the map updates and that they haven't done a good job with it.
