Question
I just put a Dual XD7500N in my car, I didn't install it though. I don't know much about it at all... For some reason every time I turn the system on, the volume starts low and within seconds is on full blast. I also hit some button...not sure which one cause I hit a lot...but now when its on radio, every time I hit the arrow button to search for a station, the display says auto then its like its scanning for stations and re programs all my preset stations and only lets me search for the presets (when i hit the arrow button, it skips stations and only goes to the re assigned presets. WHAT DO I DO?  

Answer
Did I not answer this one already?

I think this model only searches/scans the presets.  Many radios do that now days.  Some modles will do either scan all stations or all presets depending on you select/set it.

As to the volume increasing on its own that is a malfunction and requires service. It may need a replacement of one of the Integrated Circuits inside the set.  If the Dual unit is new you may want to have it exchanged for another one.  That is my opinion.

Hope this helps.
