Map CDs are just map info. Firmware update CDs do the firmware updates. (and, strangely enough... the diagnostic CDs do the diagnostics! )I have an 03 Cabrio with the 7/02 NAV CD's. When the 03 update comes out for the Nav, will the firmware also be automatically updated, or are the cd's just the map info?
I have an '02 clk with comand. The only disc I have is the one that came with the car at delivery. Are there updates available? What will a firmware update do for me. My car is at the dealer for the 'Service B' right now. Should I be asking them to update something for me?
