i installed the avic x910bt in my 2004 jetta and im having some problems ... not sure why but everytime i turn off my car and turn it back on everything resets such as my radio tuner presets, and av setting and av controls, EQ etc. .... my nav doesnt reset tho ..like my home info stays on and everything ... its just everything to do with audio/video .... anyone know what could be wrong ?
