TT5 GPS Jumping

[gigino]

Hey
I wonder if anybody has experinced this.
I have an Xda Executive with the TT5 version 5.1 installed it work ok no problem. I upgraded to the new version 5.21 because TT say the upgrade was for WM5.
I installed it first problem it well only install in the main memory could not choice the storage card.
Second problem the GPS started to jump from one road to another sometime I was in the house of someone or in a back garden.
Could not use TT5 anymore.
Contacted TT support team the answer they gave me was the the 5.21 is not compatable with WM5.
Now I back to 5.1 now I've notice that this version sometime it jumps.
Does anybody known how to resolve this problem.
Ciao
