Has anyone run into the problem when trying to buy the GO 620 GPS on sale, after entering the address and credit card the screen shows "not correct address"? I checked my account address and it is the same as every piece of mail I receive. They say wait they are trying to fix the problem, however that has been going on for three weeks. Asked if there was a work around and got the answer NO! I have a TOMTOM GPS but i'm thinking that when they stop supporting it, I'll change to another brand.
