Why I bought a Garmin Nuvi 2595LMT.
I have owned many voice command systems in my car from both Magellan and Garmin. I use my gps in my car and in my truck when pulling my 5th wheel and don't need a very expensive RV GPS.
I have many books that tell me about all the campgrounds and I know not to go under bridges less than 12ft 6 inches

and that is why I don't need a $400 plus dollar RV GPS.
I had a Magellan Maestro 4050 with voice command since 2008 and decided to look around for a new one with a few more bells and whistles. I spent a week solid reading reviews and was ready to buy a Nuvi 3490LMT ($400) but kept on reading about software issues and after trying on at BestBuy didn't see it worth $400 for a few additional features.
With that in mind I looked back to Magellan Roadmaster 1700 and a 4700 and even the 5175 Traveller and just couldn't find one that had the features I wanted.
So back to Garmin I looked and found out that The Nuvi 2595LMT ($250) had everything I like and needed and was $150 less than the NUVI 3490LMT.
