TomTom5, Ipaq 3970 & Holux GR230

I cannot get a connection between my GPS and my Ipaq. I originally had TomTom3, and everything was fine. I then upgraded to 5 and that was fine as well. This week I updated my operating system to V4.2 and since then I cannot get a connection.
I have bonded the two devices using the bluetooth manager, but when I try and get a GPS reading there is nothing. Using the GPS viewer software provided by Holux you are able to search your Com ports at different baud rates to see which one worked. It used to be Port 8 Baud 38400, but I cannot get a reading with any this time.

I have tried the removal of 5, replacing it with 3, and then removing part of 3 and reinstalling 5 as other threads have suggested but still no luck.

Please help!!
