The unit used to work. It stopped working this morning. Ive had this problem twice before but it was fixed both times by disconnecting the battery. I have not had a wrench to try it today. It worked for 3 weeks this time. I have triple checked every connection and have an independent ground in place. I have a background with installing them though my expertise falls short after that. Any ideas?

 

I'm assuming that the radio is the only thing thats not working?

Is this a factory unit or aftermarket?
