Hi, havent used my tom tom start 25 for a while as there seemed to be a problem with the GPS signal. I only realised this week that its actually a fault with the sat nav and needed updating. But when i log onto my drive it shows me the GPS quick fix but the tick is in grey and wouldnt let me tick it? I have tried updating all but it doesnt seem to be fixing the problem? The gps is ok when its plugged into my pc but of course, i need it in the car. Is there anything i can do?
