That's great! Glad they were able to help get you going! $11 certainly seems reasonable - I have one more thing to try... I called the local BMW dealer again Friday and told them my story... they gave me the Supervisor's e-mail address (he was off on Friday). He's supposedly the "go to" guy for those pesky Z3 radio codes. So I'm hoping to hear something from him today. If that doesn't pan out, I'll definitely give these other guys a try. I'd gladly give $11 for the correct code!
Thanks for posting the link!
