Query: Garmin Streetpilot 2720

Product was good for about 2-3 years. Within 2 months after installing a 2009 map update, the unit quit working. After Garmin could not fix it on line, they said it would have to be returned to be repaired. Only problem, they Quoted a flat rate of $220 for repairs. Thiis was more than the original GPS cost.
