As promised here is the custom addition that i planned for the AUX...
Since i have a pioneer head unit in the car which amongst all its features has AUX and 2 USB ports i wanted a way to put them into the new console trim and out of the glove box. Whenever the wife wants to plug in her phone she has to leave the glove box door open because the AUX cable is fed into the back of it... there isn't any way to control the phone from the head unit so she leaves it in her lap with the wire hanging out... as I'm sure you lot are all thinking thats ****** annoying!
I looked around online for ages for an OEM looking USB and AUX plug socket, i kept running into the cheap and nasty 2 in one plug things that would stick out like a sort thumb until i found out that VW use a USB and AUX plug in the Passat.
The plug connections on the back of the plug was going to be a problem as they are for the VW head units but i had an idea that i found from someone else trying to do something similar so i ordered the part and also bought a 2m AUX extension cable to reach from the head unit to the trim piece.
It all finally turned up after a couple weeks and i straight away got to work!
As you can see the connectors can just be unclipped from the back, the USB extension cable that comes with the Pioneer 8400 was long enough to reach to the centre console but it was a bit too fat to fit into the USB socket clip so i shaved down the edges with my dremel
I then dismantled the AUX connector and cut the back part off to allow me to pass the AUX extension cable through
the AUX female socket was also too big to fit in so i took the dremel and shaved off 2 sides to make it flat and then fit into the connector piece.
Once i was happy that it all sat nice and tightly i tested it out in the VW plug socket
it sat perfectly and didn't feel like it would come out without a fight so i started measuring up the console trim and then got to work again with my dremel. took a few attempts but eventually i had the cut out i needed and then fitted the new plug into it.
i was happy with how it turned out so back to the car to run the wires under the centre console, plug it all in and test it and then put it all back together. The unit worked perfectly so i put it all back together and here is the finished install.
And also a quick pic of the extra 12v socket i installed into the boot
