im gonna try this and see if it works. Hopefully it will. Do I need to be updated to z3 for it to work? I have a z1. Its the only reason i want to get rid of it though. I can't use my iPod cord that i originally got and I have the old version of the maps. I just want to upgrade to the newest version of the maps available for my car and get bluetooth A2DP streaming capability. Any suggestions???
