is this a sys file fault?

Hi Guys & Gals

I have a chinese unit that resembles a VW touch screen unit thats running win ce 6 with igo on it but the problem im faced with is it seems to always take me the long way round even if i select shortest or fastest route an often says something about restrcted area for my vehicle type even though i select car so could someone look at my sys file and advise

Regards

Try commenting out the entries under [truck] & [default].
Put a ; in front of each line to comment them out so the program won't use them.
