I have struggled with having a worthy GPS solution on my phone as well. With this thread I looked into some of these once again. When looking at reviews on Google Play none of them have stellar reviews.
In the past I had TomTom standalone units. When it was time to move on to using the phone I got the TomTom app. I had grown accustomed to the TomTom interface and maps. Google Maps has it's place and purpose, but for serious navigation I use the TomTom. I have tried Waze and it didn't thrill me.
But TomTom wasn't so great with pulling a trailer. This became very apparent traveling in the Smokey Mountains this past May. Took us on roads we shouldn't have been on.
After that trip I learned I can go to the TomTom MyDrive site and customize my routes and save them online. When I use the app on the phone the saved routes are there for me to use. Some campgrounds will let you know in their confirmation emails the best route to get there and what to avoid. Customizing my route was a great improvement, but not quite what I needed. SO then I discovered that on this site you can tell them you are doing a camper/rv and provide all your details, length, width, height and weight. So I let it plan the Smokey Mountains trip again and it skipped all the roads I should have never been on. I changed it to driving a car, and it went back to the squirrely roads.
There is an annual subscription cost. Sometimes you get what you pay for. The ability to plan on big screen and save it off for later use is great!
