Garmin nuvi 1390T (GPS receiver)

Pros: Durable, and acurate

Cons: sound with high volume will start to crack

Summary: I've had a 14 series Garmin for over a year now. I rides attached to my windshield of my truck. I drive a 3 axle water tanker truck and go off road on some very rough terrain to get to railroad sidings. It shows alot of the dirt roads that I go on too. and stands up to the abuse of my rough riding truck. It finally in the last couple of weeks developed a line that goes all the way across the screen, just under half way down. Not anything that distracts or takes away from the map that I am viewing. I would and have recommended this and others to friends and co workers. Both trains that I chase use them also.
