Somewhat like DJ in that I probably have half a dozen or more GPS units around for the cars, truck and boat. I like the Garmin Nuvi series as well and just recently, last six months, bought a Nuvi 2557LMT, which as indicated has the lifetime maps feature. The 5 inch screen was one of the main selling features I wanted, as well as lane assist. None of them are completely up to date on the maps. However I have noticed that location seem important to how fast the map makers update their products. The last time I was in Boston to see my daughter, it even had the alley ways showing but get out into western Colorado and some of the secondary gravel roads are not shown. I suspect they are more concerned with, keeping the ones sold and used in the larger population areas updated first.
I like that Garmins in that they all tend to work much the same. Very little learning curve needed when buying a newer model, except for one strange one I have on my boat.
Decide what features you want on your GPS unit. I personally don't need Blue Tooth or the ability to look at photos on my GPS. But I do like to plug in a TOPO micro SD chip into the side slot so having that is important to me. Also the last time I did the map upgrade, I found it all wouldn't fit on the GPS on board memory so a micro SD chip had to be added, which for me meant I had to down load my Topo chip to a larger Micro SD chip so I would have memory space for the entire new map upload. Not a real problem but a bit of a pain to do.
