I am new to RD's and I just got an 8500. I have it nicely mounted to my headliner now and was wondering. Should I leave it on auto or switch to highway? I do 99% of my driving on the highway, but doesn't auto work the same?
I want the best protection I don't care about false alerts so if auto is reducing my detectors range I want to switch it to auto mode.
Also, will it keep my settings the next time I turn the detector on or will I have to switch it everytime? BTW it is hardwired to the fuse box.
