hx4700 screen freeze with Tomtom 5

nuttyal

When using my iPAQ hx4700 with Tomtom 5 Navigator (version 5.20) and Tomtom bluetooth GPS receiver, the screen on the hx4700 freezes after approx 1 hour's use. This is extremely frustrating when travelling!! The software is still functional as I continue to get audio instructions.
I can only un-freeze the screen by performing a soft rest.
The problem starts again after another hour's journey.... very annoying!!
Does anyone have any ideas as to what is causing the problem??
All replies greatly appreciated.

What ROM version do you have - If you don't have 1.10 then this can occur.

In addition, what other applications do you have running?

Thanks for reply Simon.
The Rom version as shown on the hx4700 is "1.10.08 ENG"
When running the Tomtom software I don't have any other applications running as I do a soft reset to ensure that I have maximum RAM resources available.
Sad

Ok.. Version 5.2 or 5.21 of TomTom. SANDISK 512 card maybe an issue (although I doubt it). Have you tried using another SD card or better still try it on CF if you can. (I do use a SANDISK 1gb myself- so I cannot really talk can I!).

Failing that check the SD card is functioning correctly (Speed test) and that the SD card does not need defragging.

Hi Simon,
Never thought about defragging SD card!! ............ have just downloaded Storage Tools for Pocket pc and tested card. It was partially fragmented, so defragged and will try a test journey again to see what happens. Have ordered a Sandisk Ultra II 512Mb and will give that a go when it arrives.
Thanks for help.
Watch this space.
:D

Simon
Solution found!!
Tried defragging/formatting SD card as you suggested but problem still apparent.
I purchased a Sandisk Ultra II 512 Mb SD card and transferred data onto that. I dialled in a 2 hour test route and drove whole course. I didn't encounter any screen freezes during the 2 hours. After returning home, I followed same shutdown procedures as with old SD card, but this time I was able to close software and shutdown PDA with no problems.
Looks like higher speed SD card was required to alleviate problem!
Thanks for your help.
:D

Nuttyal - Glad to see that it worked.

I bought an Ulta II CF card for my Camera and the speed is incredible.

Although I do not have the Ultra II SD card, I may purchase one for a personal Xmas present!

Sounds like the same problem that affects the xda2i and the same solution (higher speed card needed).
