service menu, nav

[badboggy]

I finally got my nav retrofit to work, now I do have one question, if I go to the service menu screen, under sensors screen it shows 0 sensors for the wheel sensor, is that normal?
Also the nav looks like is a little bit behinde when I'm driving, I would say about 50-70 feet behind, is that something normal? Everything else is working great. If I go to the dealer and get the car recoded to the US specs nav, what will that get me the ETA (arival time) and changing from yards to feet, anything else? Women voice will change? I know I will need to deal with the accept screen.
Thanks and let me know,
I'm in process in getting the ipod, already bought the ice link interface and I try it and it's working, waiting on the ULF bluetooth module so I can do the bluetooth retrofit and that should be it for now. Already spent to much money.
