I've got two: nuvi 1490T (fantastic for 7 years, but just deceased due to internal plug connection/wire problems)
& 3450LMT (trying to revive due to locked map problems - supposed to be 'lifetime maps'!)
I ask myself would i get another Garmin? - 50% of mine locked up the maps! Garmin refused to help - retailer refused to help (out of warranty!)
The jury is still out!
