BM53 Radio Upgrade Problem

[rbyers01]

I recently upgraded monitor to a 16x9, nav from MK2 to MK4 and the radio to a BM53. The DSP has not been upgraded and the car is 99. Here is the weird thing when I first hook up the new radio everything works RDS, CD, Split screen Etc. When I turn the car off and back on or the radio of and back on I get no sound I can still navigate through all the screens and modes just no sound. the only way I can get the sound it so hook up the old radio turn it on then uninstall it and reinstall the new one, of course it only works until I turn it off and back on. Does anyone have any Idea what this might be.

Thanks
