Have the hard wire installed by a pro
I read the review bellow and it sounds like he may not know how to do a hard wire. And if it matters which it should not I am retired military also. My 360 detector works just fine and took a pro around two hours to install properly with its own fuse. As for the app it connected just fine through blue tooth as long as you use the settings in the phone as the instructions say and not through the app, once done correctly my phone and detector always see each other through blue tooth without issues. The mapping software looks like google maps to me and the only draw back I can see is that it relies on reports from other people using it so unless many are then speed traps may be missed. I do recommend this product and reading independent reviews about it and the 360 detector. I believe most will be happy.
