Hi All,
This is my first time on the forum and would be interested if anybody else has experienced the following error.

when I click on "street Nav" I get the following error message:

Fatal Application Error
Application MOBILENAVIGATOR.EXE has performed an illegal operation and will shut down.
If the problem persists contact the program vendor.
Exception:0x80000002
Address: 03F92424

If so how do you rectify it ? or did you get it rectified under warranty

thanks ray
