I have been using the Nuvi 465LMT since February 2012 in both the RV and the Auto. I enjoy the map updates and traffic. The 465 has worked well for me.
I previously used the Nuvi 680 since 2006, which worked fine except the cost of map updates. Never updated the maps, worked ok, but getting old, like someone else I know.
Recently compared the Desl 560LMT and the Desl 760LMT. Decided on the Desl 560. First use has been with the auto for familiarization. Next week it will get it's first use in the MH.
I like the features on the 560. The split screen sign feature is nice, along with other warning notices. Just planned a 1k mile trip using streets & trips as a guide of the routes I was interested in taking, with many stops between start and finish without any issues.
Paired Bluetooth without any issues, and the 560 has a voice dialing option, which worked the first time.
Garmin needs to send ole Jill to English language classes. Voice commands are better than the 680, and some improvement over even the 465. The volume and brightness adjustments are more than adequate. The speaker sound is a lot better.
See how it goes in the long haul. Been using Garmin for years in boats, autos, and RV's. Another nice function on the 560 is traffic avoidance options, which can be rerouted using miles or a different route. The 465 has the auto traffic avoidance which rerouted us on one occasion around an interstate traffic tie up on a different route which worked great. Now with the 560, I can choose how far and/or the route to avoid the traffic.
MH toys sure are fun. Gps takes stress free traveling to a new level. Trust with Verification is the only caveat!
