below are the errlog from my gmxt
Umm... brother Soulquarianz,
I think I've mentioned peculiar quirks about GMXTs before, but I don't mind writing this again. Sorry, this will be a rather long read.

My cPOIs are designed following standard Garmin techniques, i.e. GPX files generated by Garmin MapSource and POIs by Garmin POI loader. Of course, I could have used other third party software to construct the cPOIs but in the interest of ease of waypoint maintenance and updates, I chose not to.
The procedures that I followed from the various tutorials on the Internet are guaranteed to work on dedicated Garmin GPS models like Nuvis, Streetpilots and Zumos. None of the authors have tested them on Garmin Mobile XTs, which behave differently than non-PDA/smartphone based GPS units. The US and European maps that the writers used are most probably official Garmin compiled maps (whereas MFM uses CGS Mapper, if I'm not mistaken).
The very fact that GMXT devices are unable to play audio announcements is already an indication that GMXTs are not 100% compatible with features that Nuvi units can normally perform.

That said, I have access to a Nuvi 310 and a 200W for testing purposes but I do not have any Symbian/PPC/Palm/WM/Linux based GPS devices to test. Memory access violations can be caused by external factors - it could be other memory resident apps in your PPC, it could be the your device OS' being unable to handle memory allocation errors (causing your PPC to crash), the GMXT software's limitations or even faulty physical RAM.
A POI is a POI, regardless of its coordinates and I am unable to explain why your unit crashes upon reaching the Putrajaya areas. (Does this happen elsewhere or only upon reaching the Putrajaya speed trap POIs?) If you search this entire forum, you will not find a single complaint from Nuvi users pertaining to their devices crashing from the use of custom POIs.

Custom POIs are not programmable executable files or scripts - they are merely POIs with proximity distances, speed threshold and special icons which are handled by the Garmin GPS software. I would like to highlight again that GMXT is a software that is executed by a general purpose operating system, such as Symbian OS or Windows Mobile.

The Garmin OS used in Nuvis and Zumos is a proprietary and embedded operating system that was designed to work perfectly with the Garmin's hardware. Nuvi models with MP3 playback capability can process true TourGuide files, in which the user is presented with an audio description of special points of interest, e.g. if you're within range of that POI, it will playback the audio file if he or she wants to (I believe a TourGuide icon pops out on the screen).
I don't know if TourGuide files can be played on GMXT units - if they cannot be recognized on GMXT, you don't know what you're missing!

My personal advice to those who want a fully functional, in-car navigation GPS device: please buy a Nuvi! (It doesn't have to be a brand new one) for your vehicle. Use your GMXT enabled Nokia E71/Samsung Omnia/whatever for pedestrian or casual navigation instead.
I'll give you a simple analogy!

If you have a cellphone with a built-in digital camera, ok, let's say a Sony Ericsson CyberShot phone - you can take acceptable general photos and that's about it. Good enough for quick-and-dirty snapshots, but hardly considered quality results by a discerning amateur photographer. (I can vouch for this - I have two Canon PowerShot consumer digicams, an S3-IS ultrazoom and an A620 compact and not even the Sony Ericsson CyberShot c905 can get close to the photo quality of either dedicated cameras).
Even with a 8.1 Megapixel camera onboard the c905 phone, I can guarantee you that the photos will not have the same fine resolution, sharpness and low digital noise of a dedicated camera, e.g. an older Sony CyberShot digicam even with only 5 Megapixels. Sony Ericsson is not dumb - they would never make a cellphone with a camera that will rival their own Sony CyberShot digicams! You also won't get the same photography features (e.g. ISO override, manual mode, aperture priority, shutter priority, depth-of-field, etc) from a cellphone camera that a dedicated camera can offer.
Just to illustrate, I recently purchased a Sony Ericsson G705 phone as I needed WiFi, HSDPA broadband access. Oh, it's got a built-in GPS antenna too and runs Google Maps/Google Earth. There's a trial-ware Wayfinder mapping software embedded in the phone that has turn-by-turn voice prompts but I never bothered to use it. Why? It's nowhere as good as my Nuvi 310 with MFM in it.
And the phone's GPS is nowhere as sensitive or accurate as my Nuvi 310. At best, I could get my location within 30 meters (occasionally) with the G705, but I have experienced satellite fixes as accurate as 3 meters with the Nuvi. That's a 10:1 accuracy advantage the Nuvi has over my SE cellphone.
The moral of the story: you can't have your cake and it eat too.

GMXT based devices are indeed handy, they are multi-functional, you can make phone calls with them, you can run spreadsheets and surf the web with them, you can easily slip them in your pants pocket. But when it comes to serious in-vehicle, GPS use, one shouldn't expect GMXTs to perform exactly what a Nuvi can do.
Even then, the Nuvi has its limitations and shortcomings. Most models cannot perform track logging. Those that do, won't do super-accurate 1Hz track logging and are not suitable for outdoor use for hiking and trekking.

That's when the Garmin eTrex models for example, come into the picture. They are also meant to be hand-held, weather and shock resistant for use rough use in the outdoors. Some models also have electronic compass, altimeter and barometer features - and a few are equipped with GMRS walkie talkie functions.
On the other hand, the eTrex units are not ideal models for in-car GPS navigation like the Nuvis are!
