I found this site just by chance and after much debate and much skepticism, I pulled out the ol' Z1 and did the bluetooth update, rewired the plugs and VOILA! my system is now bypassed.....NO ONE in town could tell me how to do this, or they just didn't want to, whatever the case, it works flawlessly now and it is all thanks to this site...

 

and NO MORE ECHOOOOOOOOOOOOOOOOOO!!!!!!!
