Anyone out there have hands on experience with both the F900/F90 and a Z3? I've been an owner of the Z1 since shortly after it came out. I've been relatively happy with it and now have the need for a unit in a second car.

 

I've really liked the NavTraffic features specifically traffic speeds on the Z1, but I'd like to have the newer voice features in the F series.

 

Any suggestions?
