just installed 2 beltronics rx65 radar detecters and i used the hardwire to power it up. the problem is that the power keeps reading low voltage when ever i hit a bump in the road then it shuts down and restarts. I double checked and triple checked the wiring and even had beltronics send me a new hardwire and still this happens. does anyone have this radar and has the same problem with a fix. I believe it has something to do with the power jack but when i shake it nothing happens. I tested the voltage and thats fine.its now going directly to my battary and still the same. please help. sould i get a different radar.
