Awesome, looking forward to reading about what you put together.
It turned into a pain in butt of a job.
made great progress with the right kit, i used -
Autoleads PC5-121 - Jeep Cherokee, Grand Cherokee, Wrangler ISO Aerial Adaptor (PC5-121)
Connects2 CTSJP00C Jeep Commander, Compass, Grand Cherokee Steering Control Stalk Adaptor
- Additional Stereo Patch Lead: Free CTMULTILEAD.2 (CTSJP00C)
got power, steering wheel controls, DVD, USB, SatNAv,, Radio etc with very good volume via the inbuilt amp - But no voice from satnav or on handsfree phone calls - other party could here me though.
spent a day and a half trying to sort that out - including several hours on the phone to pioneer - who were also stumped for a solution. kept saying something about it wont work (ever) due to the inbuilt amp reveresing polarity and messing up the mobile and satnav voice!!
had a look around on loads of websites and forums and solutions ranged from deleting google apps from phone (really?) to switching from android to I-Phone. tried 4 android handsets and an I-phone - no success.
Then a light bulb moment (my son did anyway) - if its a speaker polarity issue, swop the speakers around. did a quick google and found -
(my great thanks and acknowledgement to the original poster of this solution)
Swapped the connectors as suggested in the video (slight colour differance on my unit) and hey presto!! works like a dream.
