Done my Connects 2 yesterday I thought it was quite easy except for a few bits of trim that were being stubborn. Never had the Honda loom as there was no way I paying £92 for a bit of cable and a little bit of solder does the job nice.... I was quite surprised and a little concerned that the Audio button did not work with only the connects pluged into the stereo but after I wired in the 3 cables for the satnav everything was fine, I wonder why the control for the audio screen is linked through the satnav plug

Thanks to everyone for the guides I literally could not have done it without them.
