I have a 2006 Audi A3 with the Concert II. I purchased the Dension Gateway Pro from Enfig and for the most part, it works great. My only issue is that the phone calls do not play through the speakers. It picks up the voice from the microphone, but I cannot hear anything anyone is saying. You can actually hear that typical analog "hiss" that you get when a signal is being amplified or enabled.

For a short while I had the Dension Gateway 5. It would play the phone calls through the speaker, so I know my speakers work. Unfortunately, it would never turn off and ran my battery down.

The readme text file says to enable Dip switch 4, however this changed nothing. In fact turning any of the dip switches on made little or no difference to how the unit worked (at least as far as I could tell).

I should add, does anyone have an idea how to make this work?

BTW, this is a great forum.
