Summary: I purchased the Nuvi 275T because is has the European and USA maps loaded. I was expecting to use this device as I walked through the streets of Barcelona, Spain. Other than being used for a clock (it grabs the time from satellites), I found this device to be utterly useless.
Summary: Just used my Nuvi 275 in London and I must say that I was very disappointed with it operating in pedestrian mode. First it takes a very long time( >5min) to lock when you come out of the tube ( subway ) even in an open area.
Summary: I got the nuvi 275T with great expectations and excited about the cool new traffic alert feature. Unfortunately all of this was flushed away very soon. 1. The GPS keeps giving the message "Poor satellite reception" every 15 mins. It recovers though, but well it keeps happening so it is annoying. 2.
Summary: First the good: The Nuvi 275T is a capable navigator that gives precise spoken instructions and seems to find good routes to specified locations. The display is nice and even readable in adverse lighting situations.
