I recently sold my Valentine One to pay for other car mods. The radar was a few years old, so unsure of the version but it worked great and never gave me a problem.
The new owner says the Valentine one worked just fine the first day, however the second day of use the radar has thrown an "E" error code and doesn't work. So I'm stuck in a difficult situation. Any input? It's hard to take back a radar detector that worked 100% when I shipped it out.
Help would be much appreciated. I searched around and got nothing really definitive.
