Hi guys! I'm new here and I hope you could help me with this. I just recently had a dvd system installed in my SUV. However, the installer had to use an FM modulator for the audio to come out thru my car speakers. I know my HU has an auxiliary input and i just need an adapter. The audio works fine but I was wondering if the sound would be better i.e. digital if I make use the auxiliary feature in my HU. Thanks!
