Stock HU ERR'd out, but i FIXED it!
Dont let those dealerships rack up hundred dollar repair bills when it only takes a couple painstakingly slow hours and a Q-tip to fix.
If I get some more time and it's daylight outside, I can provide pictures to walk people through it, if need be.
I've had the same ERR error from my Monsoon CD player so following Kip's advice, I disassembled my Moonsoon unit (to where I can see the CD player lens) and gave it a good cleaning (blew off the lens with compressed air and wiped the lens with a reading glass cloth [microfiber would probably work but I wanted a finer cloth]) and my CD player is now finally able to read any CD I insert.
I've tried the CD cleaner (the CD with a brush attached) with no success and tried the compressed air method (sticking the straw inside the CD player to blow off any dust on the lens) and from disassembling the unit, there was no way that the compressed air method would work since the lens is far back in the unit.
