I have a Magellan GPS with lifetime updates/road alerts etc. Only problem I have is it needs to be kept plugged into 12v as battery memory has a, well, short memory. On the other hand my 2011 BMW528i has a very pricey Nav system which requires an equally pricey software update every year, if you think you need it. It is more sophisticated and adaptable but for our RV trips the Cheapie Magellan(Maggie) does the job. I wonder if the OP has one or more free downloads to update the software??
