Query: defective

I have had mine for 2 years. It has never completly failed but always seams on the edge of it. I have had all of the problems listed in the other post but not quit enough to trash it. It is VERY slow to lock onto a sat. it freezes up and turns itself off for no reason. Periodicaly it will route me off the interstate to secondary streets and back onto the same interstate. My next one will be Garmin without a doubt. At first I was always afraid someone would steal it but now I am hoping someone will. Read these post and read the glowing reviews for the Garmin nuvi and what a difference!
