I may not be the only one to find that GPSAssist.NET crashes on start up on an iPAQ hx4700. The problem has been found and characterised in the Brighthand forums - it's a bug in the ATI graphics driver DLL that affects much if not all .NET software.

I've put full details in the GPSAssist forums here and people may like to follow that thread for any discussion. However, the key information is:

I've finally had just one chance to try GPSAssist in car - and the results were not good. With all the options on, as I had been used to with my iPAQ h3970, Navigator was utterly confused as to where I was. The problems went away when I started Navigator without GPSAssist.

I haven't yet had chance to test things more carefully; I will get a chance to do so later this week and will attempt then to find what the problem is. I have since found and solved a problem with my TomTom Traffic / GPRS setup, so that's one problem I did have that's sorted out. I haven't had a chance to test GPSAssist again since I sorted this problem.

There's various possibilities for the cause of the problem, including the 1GB SD card I'm testing.

It is of note that the registry change mentioned in my first post fixes performance issues with Microsoft Reader. With the related feature in the graphics driver known to be buggy, I'd recommend this change to any iPAQ hx4700 owner until HP release a fixed graphics driver.

I've edited the thread title as I wonder now whether there's a more general WM2003SE issue with GPSAssist.

The instability in my system has now been found and sorted; the 1GB SD card I was testing was to blame. Substituting my 512MB Panasonic (Integral brand) SD card which contains the same map and POI files meant things were much more stable.

However, my hardware buttons don't work in GPSAssist 2.1.1.14. CheckPOInt 2.0.2 can still record POIs, so it's possible to get hardware button presses to pass through to add-on applications. I find that my buttons (even button 5, the record button) simply carry out their default functions - such as, on my machine, opening Pocket Informant in the Calendar view if I press button 1.

It's possible that this is the result of a change in Windows Mobile 2003 Second Edition (or to the version of the .NET Compact Framework shipped with it). This is why I've changed the title of the thread. Alternatively, it could be an hx4700 specific issue.

Clearly the handling of hardware buttons is different on the hx4700 to other Pocket PCs I've used - the Operating System has built in support for long presses on buttons 1 to 4 - which can be configured as buttons 5 (long push on button 1) to 9 (long push on button 4).

Does anyone else have positive or negative experiences with GPSAssist on WM2003SE Pocket PCs? If so, please post them below. Meanwhile, I will report my findings to the developer of GPSAssist.

I have finally found the problem with hardware buttons in GPSAssist 2.1.1.14 and my iPAQ hx4700.

Something had created a lot of seemingly redundant entries in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Keys - after a hard reset, there were just keys 40C1 to 40C9 in this key. Once I deleted all the other entries with a registry editor, my hardware buttons in GPSAssist worked.

I have kept a copy of what was in that registry key, just in case. I haven't got hardware button support working in SOTI Pocket Controller Professional 4.12 after deleting the other keys, but I'm not sure that worked before my registry edits. I have reinstalled the 'device' end of the software with no effect.

Unstickied - with the launch of Navigator 5, I think everyone for whom this is of use will have found out about it by now. The new 1.10 ROM for the hx4700 should sort out the graphics driver problem without needing a registry edit.
