This post over at benzworld got me started "http://www.benzworld.org/forums/audio-telematics-forum/1313173-how-guide-cell-phone-upgrades-plug-bluetooth.html, then I was able to download and print the actual install instructions at this address "http://home.earthlink.net/~phdwebsite/phone_bulletins.htm". I don't think there is much more I can add to this information other than to help someone with a specific question for the r171 install. The biggest point I wanted to make is that it is an easy install for me. Spend a little time doing research and then some hands on time with the instructions and I believe just about anyone could install their phone.
