Summary: We have a Magellan Maestro and felt that it was time to upgrade to a unit that tells you the name of the streets and distances. The RoadMate works basically the same way as the Maestro, which is why we decided to go with it. The only pitfall is the double process in updating the maps. Very happy so far.
Summary: I owned other makes of GPS's and those not lasting long. I rented a car that had a complimentary Magellan in it and I liked much better the way that it provided advance turn advice, made corrections when a wrong turn was made which was frequent with me, etc. (None of that annoying "recalulating.") I purchased a previous version of the Magellan Roadmate very similar to the 5045-LM and used it for about two years.
Summary: So far for me it has been great, the 5" display is a plus specially when your vision at night is not that great. the Lifetime Map is a great feature. The satelite signal in my area was very fast, the controls in the menu area simple and the traffic information is divine. The price was reasonable.
Summary: I bought the Magellan RoadMate 5045-LM GPS out of nasessity because my old Magellan Maestro 4370 had died on me when I was on my way to pick up a large settlement for the law firm I work for and God forbidd, gotten lost. I also bought it for the free life time Maps. My problem I mostly incounter with Gps's I've owned was that after a while the model is replaced by a better model and the company that producese it no longer provide map updates for it.
Summary: As someone who owns an Android phone with Google Navigation I thought my owning a stand alone GPS days were over simply because, well, I have a GPS on my phone for free so who needs to buy one now. Well recently my job now requires me to drive up to the northern suburbs of Chicago regularly as well as parts of Chicago which I am not all that familiar with.
Summary: When My friend and I take short ROAD TRIPS and we sometimes get lost. The first time I used it guess what. No more U turns or stopping for directions. I saves a lot of frustration.And the traffic updates worked great.
