Well I know this ... it only goes through my subs though with the thumping and only does it on ipod source it also does it when it comes to the end of the song and the radio does the change on its own .... also have a little engine whine but if i run a ground and put it on my RCA's it doesnt do it near as bad !!! I juss need some insight !!

I also noticed that when I put in a dvd my bypass it works but when i go to accelerate it stops playing and says its prohibited to view a dvd while in motion or w/e im thinkin my ground is crappy ?

I live in Houston and when I go to look for an address it says to put the correct CD in so i put the other one in ... well to be short I got to select Option number 5 which is Texas and it says its not avaliable on that disc ... well I put the other one in and it still doesnt let me choose it ... My volume knob wants to work when I push up and turn it and it has a whine noise from speakers.... Im beggining to wonder if this radio is worht this headache .... PLEASE HELP !!!

When I scroll through the artist or change a song or do anything on Ipod source my subs make a very annoying thump sound but when I go to change the song and push next it make a double thump sound. Its driving me crazy !!!! any ideas !! Thanks
