Hi, first attempt at a retrofit. I would like more connectivity options in my A4 so I challenged myself to retrofit AMI. I sourced all the correct parts and have installed the AMI, with one slight problem. The cable 8K0 051 592 has a wire thats red/yellow that has a female fuse terminal. The manual supplied from Audi suggests to add this wire to the middle brown fuse block at the side of the dash. Either in slot 1 or slot 7 if slot 1 is occupied. Now my question is, is this correct? As this slot is totally dead. Ie there is no fuse or any other live wires here. The kit also came with a fuse but no mention where this goes. Has anyone done anything like this before as I've searched and searched and cannot find anyone who has done this to their B8.5 before, or if they have, have not told anyone else how to do it. Failing this, the AMI is not yet coded in, if I connect an iPhone to the AMI will it show charging? Just so I know the installation is correct before I get it coded in? Thanks for any help.
