Iguidance 4.0 on Touch, refresh problem need help.

[cmai]

I just got Iguidance 4.0 installed on my touch and it does not seem to update the direction as I go as fast. It would tell me to take a street, then after I take that street, I look at the device and my position has not move to the new road. I have to wait for like another 5 minutes before it refresh. It that a software problem or am I missing something?

Thank you
