The Garmin RV 760LMT can search for it's database for Rest Stops and Parking areas.
I downloaded Flying J/Pilot POI's from POI factory for free and can now search for them also via a icon.
Huge upgrade when I went from Garmin 1450 car in the RV to a RV 760LMT. Also the free basic weather and severe weather alerts are a real plus when on the road. For $4.99 you can purchase advanced weather with radar with RV icon shown on weather/radar map. It does cost cell data, but when on unlimited Verizon not a problem.
Will be trying out traffic alerts and re-routing this week as I travel from Cody WY to mid ( a few weeks) and southern CA and then on to Yuma AZ for wintering.
Voice command is a easy feature to use and find places. You can say the street address city and state in one voice command. She then shows what it thinks you said. You then pick the line number for the correct one, or say "back" and try again. High A/C dash fan noise can effect it's ability to unde4rstand. 9/10 times it it understand you correctly. DW and I both like it. Highly recommend it for RVers.
I also own a Garmin 3597 LMTD for the toad. The comparison between the 2589 LMT and the 3597 LMTD is here: Garmin nüviÂ® 2589LMT vs Garmin nüviÂ® 3597LMTHD
It can be purchased here Garmin Nuvi 3597LMTHD Refurbished with Lifetime Maps The GPS Store
for $ 179.95
The 3597 LMTD does have digital traffic updates which is an improvement over the 2589 LMT and the RV 760LMT. HD Digital traffic updates are more frequent and give you a better chance to use the re-routing feature.
Alone this one improvment is worth the extra $$.
Be sure to plus up whatever Garmin or other GPS you choose for your trip with custom POI's. Join the POI factory POI Factory | new & interesting places for your GPS
