Hi there I have a pioneer avic x1bt installed in my R170 which I want to remove and return to something a bit simpler. Does anyone have any experience of this unit? I understand it has a wired microphone which emerges next to the roof light, a Bluetooth unit which must be hidden, a GPS unit which emerges passenger side between dash and windscreen and a hideaway unit which I also cannot see. The unit is apparently still worth a tidy sum on eBay so I wish to remove in cleanly and sell it on. Any advice on what panels would need to come away or how difficult a job this is would be great. I've installed and removed simple head units before but am I taking on too much?
