I have had my d3 installed for about a week now and last night on the right home from my girls friends house the sound output through the harness just stopped working. There wasn't any sort of event that triggered it. And now it does it like every 5 mins. 5 mins on then 5 mins off, you get the idea. Has anyone ever had this problem or have any suggestions. Any help would be much appreciated.

The video and all of the other features work just fine but there is no sound!!

Thanks In Advance.

Check to make sure all the wires are secure and not shorting out

do you think that only using the factory ground in the harness and not running one to the car would affect it??

Not if the D3 is the only thing you changed

i just switched out my stock head unit for the d3 and long before that (months) put in new Memphis speakers, no amp.
