Have two Garmin's both with LMT. One for my Jeep and the RV760LMT for the motorhome. I actually like my nuvi 1490 better. The extra size of the 760 is nice. I have had zero problems updating either one since the initial download. It downloaded an icon named Garmin express and that works great. Have e-mailed Garmin with an error on a route and they e-mailed me back fairly quickly thanking me and informed me that it would be fixed on the next update which it was and it was all free as advertised.... ..Good luck with yours.....Mike
