Mra Navigation

If pondering that question is what's keeping you up late, I think you need to stop putting ice in your whiskey.

 

I use MRA and a Tom Tom 550 too. I ended up taking out a one year subscription to the MRA Nav App to check it out. It is handy in that you can see all of your planned routes directly in the Phone Nav app and it works well as a phone Nav device. Voice commands to my Cardo unit come through well too with no lag. It also keeps your waypoints unlike the "track" you get when sending your MRA route direct to Tom Tom MyDrive.
