Hey Axxantis, thanks for posting this. I got mine at about the same time as you made your first post, and I've also been having a lot of problems.

I had an rx1950 PDA, and unfortunately it's not up to the speeds of your nice 624mhz machine. I found my SDG-810 went to Com4 384000 baud. Some of what you say though was quite similar to what I was experiencing. I had no problems accessing the maps, planning trips or doing anything else with TomTom 6, until I actually tried to use the GPS. As soon as I set it to the SpecTec driver the whole thing would work for about 5 seconds before it would practically lock up. Things still responded, but very very sluggishly, taking a minute or two to complete 1 key press. And as soon as you set TomTom to use that driver it does it on start up every other time, so you only have a few seconds to disable the GPS before it freezes if you're using the maps from the mini-SD card with the GPS attached, plan out the route and then re-enable the GPS and start going. It will then advance in fits and starts and go very slow in general.

I tried installing TomTom 5 as well, but with the same exact symptoms. iGuidance unfortunately crashes everytime I try to use it, probably because of the lack of memory. I was able to find that Mapopolis mostly works, but it has serious lag on the SD card until you set it to 'load maps into memory' after which point searchs go down from 2 minutes each to about 2 seconds. The maps are very old, 2 years for the latest ones, and the interface is not car friendly - it does not have slant view either and they don't let people buy any maps that they do have that are for other places now. It really seems like the SD or Micro-SD card are the lag points. Wififofum also seems to lag with the GPS enabled.

I've been using TCPMP with this PDA since I got it with no lag though, but I don't know if that really means anything. I tried to do as you suggested, I upgraded my MemMaid from version 1.2 to 2.0 just to get that 'SD/MMC Transfer' tweak setting, but unfortunately its greyed out set at 64kb :(. I tried reformatting the microSD to FAT32 but it also seemed to have no effect.

The microSD card I have is a Kingston 2GB one I bought seperately just for this GPS adapter.

So in summary with TomTom 5/6 its impossibly slow with GPS enabled, works great without it when doing demos or any other functions, once its enabled the entire program lags (like 1 second = 1 minute) including the menus. As soon as I select 'SPECTEC GPS DRIVER' in the NMEA GPS selector in TomTom, I'm screwed - If I leave it on it gets very very hot on the back and the battery gets drained very quickly (same if I set the right Com port/baud rate in Wififofum) Mapopolis works, though also had SD lag which I worked around (and it has bugs since its not technically fully WM5 compliant). Installing any of the programs directly to the MicroSD seems to have even more problems.

I'm using the modified SpecTec drivers for the rx1950 and a few other PDAs from their website, "HTC Charmer PM200, Qtek S200, HP 5965, HP 1950, HP 2190, Dopod 900, ASUS p535, Treo750, DELL x30, TOSHIBA 1830" (so the same as you have I think).

This is an entry of all the things I've been trying over the past month, though I may have missed some things. It really sucks that it can't really do it, glad to hear you got yours working but if anyone has any tips or suggestions please make them it's really appreciated :).

Thanks,
Peter
