Hi all.
first I am here to learn and get this piece of gps device working.
You can probably assume that I am a completely Nubs, but please do try to read my problems carefully, and if you still find me nubs because I did not read the tutorials/forums carefully, then please do post the link here.
I am not discussing anything about Mapthis! softwares, here yet.
Just a pure GDML 0.5.02B (the latest)
I live in Auckland, New Zealand.
It seems to me that, a lot of GDML and Mapthis! are optimized for USA and Canada... somehow, I feel that way....
I've been trying to do various of stuffs. All I want is to get it working. as smooth as possible.
First, Google Map. Somewhat somehow I got the map downloaded working. I followed the guideline posted somewhere here. 
Next, Geodata. WTF is this to be honest. I've been searching for ages on entire google search, and yet no one is explaining any of this. I know nothing about Geography, I barely know Lat/Log are, at least thats how GPS works. and maps are just 'illusions' to show on screen. at least thats how GPS works)
=Question 1.
I thought I downloaded the Map that includes street names, etc into JPG. Ain't I correct?
From the previews of my downloaded map. It looks I am right. (i.e., st names, etc are 'embedded' as JPG picture)
=Question 1.5.
I know what POIs are. such as Patrol station, macdonalds, etc. Google obviously knows big names such as 'schools' etc,
Then is there any ways to simply RETIREVE ALL of them (e.g., retrieve all POIs from Auckland area) ?
I can not find this as this is more to do with Google disallowing abusive behaviors?
As well, Google bans IPs (for Sat image) whenever I download more than thousands (out of 10s to 100 thounds), which means, it is impossible to download. and the Pop-up seems to be very buggy, there are no automatic re-trieve, i need to click OK button to proceed to next step,. thus I gave up on Hybrid images.
=Question2.
Then WHAT is Geodata for? hmm. maybe for searching St names? maybe showing names into 'TXT' into (already embedded) JPG maps??
I am lost here.
I tried to open the geodata.dat, it's unreadable in normal text editor.
I also tried the 'working' geodata.dat from other countries (i.e., the one from Netherland, i think), still, unreadable.
I know that all USA and Canada and Netherland dudes have noproblems of 'Geodata' because GDML said so. (which probably means the authors have retrieved nearly all, and linked on the website)
In my case, I need to get Geodata manually, using Google (semi-manual)
=Question3.
I got the map size of 200MB of Auckland, NZ. Not bad. I still don't know what is Geodata for.
Still, I now go to Geodata button.
Step 1/3 (Load the map) I did, good, loaded.
Step 2/3 (Select) shows 64 segments.
Here, Why can't I simply select all and download all ?
I can not find the way to select all, or any ways to automatically download Geodata.
Further serious problems. whenever there are some oceans/seas in one of the segment (out of 64), The download simply fails after it sees 'merely' 20 !!
Why is this? there are 5776 (75 by 75) to be requested, and I why is it simply failing just because of 20 ??
Step 3/3 You can not overwrite/save geodata.dat. I need to either delete or rename the geodata.data before I can refresh the new.
Yet. I still don't have any clue why I need geodata. But one thing for sure I need it, is because people seemed to be wanting it !! damn it!
Additional Question........
Route/directions/etc:
To do so, I need internet to retireve and Manually select TO/FROM from google-map, then download into PSP.
Erm... I am a bit lost here... Why would anyone wants to 'manually' download the route and finally fake it on PSP-GPS...?? I think this sounds silly.
But to me, this looks like,
"while I am driving, and I want to go somewhere, and need to know the directions and locations,
I must to go back home, go to google-map and search the direction, and download that info to your psp, get back to my car, and drive using the updated PSP-route direction ?????????????? "
Shouldnt it be opposite way around...? Again, I'm lost here. To my knowledge, once the maps and geodata(whatever it is) are ALL stored into PSP, the psp 'should' be able to perform the 'basic' ShortestPath Algorithms to find the route/directinos?
Actually, does Mapthis allows users to enter Street names and find some path?
I need some serious help here please.
thank you very much in advance!!!!
