Thanks Mixbreed! I also dial that way to access my cell-phone's extensive phone-book. However, it's a pain ...

PriusChat lists a company which has "broken the code" (actually, it's a plug-in device) to open-up full nav & phone operations (to the passenger, of course!) while driving down the road, however, they are having difficulty with the 06 system. I expect success with the 06 in the coming months!

Stay tuned
