I have a TOMTOM 1515TM and was working fine and I keep up with updates that are available but since last update about 2 weeks ago it has trouble finding a valid GPS signal and does not always follow the route I have selected. It seems to be searching for a signal and the speed does not always indicate the correct speed.
I have gone into GPS Status and it shows at least 4 satellites but seems to be searching for more. What is the problem and how do I fix it??
BTW - I'm in Canada, on the east coast and this unit was working fine until recent updates.
