I've had my Rand McNally for a few years now....its been just OK in my opinion and lately has started to freeze up on me causing me to have to reset it completely. I've entered my vehicle description but still get sent down very curvy roads But maybe that's all that's available. One thing that I've reported to Rand is that when you indicate you are towing, in my case, a "toad")...in Calif, it does not change the max speed limit to 55. Not a big deal for me but for others who don't live here, it might cause issues.
