Does anyone knows how to connect HU through acc or ignition to my new Octavia?

The HU is now connected, but I can turn it on/off without putting key in lock.

There are two +12v wires and i tried to switch them, as it says in manual of my HU, but there was no luck.

The HU is Pioneer Meh-P5100r.

What should I do?

Thanks!

P.S.

What is the use of 2 wires marked "?" on pic?

Is Maxi-DOT display connected with the OEM radio through them?

Finally, sorry about my bad english.

if you can turn it on anytime then its down to the stereo, does it lose it memory? if so then swap the red and yellow wires.

one of the wires you highlighted as "?" is 'illumination', it dims the H/U display when you turn your lights on. not sure on the other one. will google it

I'd say that the other one marked "?" is an attenuation for mobile phones. I thought that I read somewhere that you have to swap the red and yellow wires on Pioneers to make them work properly.

Stereo dosen't lose memory.

I tried to swap the red and yellow wires, but everything works like before.

Before Octavia I had Fiat Marea and there was a problem with wires and after I had swaped them stereo worked through ignition.

Which of the 2 wires marked "?" stands for illumination, left or right?

I wouldn't want to connect it wrong, because I don't know what can happen.
