Seems alot but then again I've always done mine, it's not hard at all, if I was in your shoes I'd have a go first if that fails then get in the professionals.

All you need is

Power from battery
Phonos and remote from stereo
Earth - find a decent spot in the boot. I always remove a bolt. Sand it to. Are metal then reattach the bolt

It's honestly easy. Will non of ya mates help?

I use to do things like this 30 years ago but with all the things like ecu and can bus electrics it scares me a bit before it you did anything wrong you just blown a fuse now it seems you can knacker the ecu up
