Not at my car, my cigar lighter is allways on. I can carge my mobile phone anytime there and yes, i control it
with a multimeter and it has 12,6V.
The Radio have not an acc wire, its controlled over the canbus system. The acc port is bridged on the Quadlock with the power cable (on carside). When i connect the two optional Red wires, the radio stays always on. (because
the acc is original bridged with +. Funny is that i can disconnect then the Canbus adapter completely without any dysfunction.

Hello and no problem

Thank you, i will wait for the device and cable and give you then information if it function then or not ^^

For future, how about to get in a function that allowed to turn on the radio without acc signal, so the
radio can turn on without key.
The Original radio the acc wire was bridged with the power wire, so the radio can turn on every time.
It has a direct canbus connection and read die acc position over canbus.

best regards

Hi,
we will arrange to send the canbus decoder and modification power cable to you ASAP.
Currently we know that there is not a radio which turn on without acc signal, even the car start with the power button, not the key.
If you have any news about this function, please share it with us. Thanks.

Hello

The new modification power cable arrived and after some research the sound works now perfectly.
On the Cable is now a "filter" box, but its not a filter, it is a amplifier that can adjust with the two
adjust capacitors. With them i adjust the Output volume to the prefect level.
I had to newwire the Chinch system because you have here 2 Stereo amplifier but feed them with
1 Mono signal each. by that the signal was also reversed and cancel each other out. After rewireing it, its works fine

So first problem solved

Second was that it turn off after turn off ignition. I asked audi and at my model the acc signal goes over the canbussystem.
The Canbus adapter use the ignition signal not the acc signal over the canbus system. Is there a way to change that?

Best regards
