I don't know what happened the unit just completely went south and it was working fine up until Monday with no warning. I pulled it out today exchanged all the fuses and tested the 12v ign lead (14.43 switched on), 12v bat lead (12.21 without turning the key) , and the ground lead. I checked the fuse in the back of the unit and the one from the fuse box under the steering wheel. I have it installed in a 04 Mustang and its been repaired once already. I'm thing about selling it if it has to get repaired again. NO ONE shouldn't have to go through with this kind and this is getting old anyway. I bought the CNSD-100FM sd cards new and haven't used them yet...

Oh sorry I forgot to introduce myself... I'm JayMax03 I'm a newbie when it comes to navigation units and I barley use the navigation part of it anyway. I saw this forum a lot but never really signed up for it since I never owned a nav unit before til 2008 when I purchased this one.

Can someone please help me I want to get to a solution before I send it back for repair?
