Customer Question

I have a DNX5120 in my car. Recently I was at work and keyed the mic on the radio (commercial grade walkie/talkie as I work in a wood mill) too close to the dash and the radio/nav system went out comletely. I'm thinking that I probably blew something with the resulting EMP. Is there a fuse or something I could check or is the system totally hosed? The 15A power fuse appears intact.

Hi Sam and welcome to JustAnswer,Thank you for the question and your patience. Should you still need assistance for information purposes only...Initially, have you tried a hard RESET?
Customer: replied 11 months ago.
Is there an easier way than taking the whole thing out, disconnecting the wires and putting it back? It's working now after that.
Expert:  Louie replied 11 months ago.
a RESET as it is both a test and a try of a fix. As it implies, a reset would force the unit to revert back to factory defaults removing glitches and config errors but would include memories, presets and user preferences. After a reset, the initial setup would have to be performed. May have to be done a number of times.This is very critical - a reset however would not be corrective of an internal hardware concern; but it would be confirmed. In some instances, it may even expose other issues.
