When I went to my memory stick to load up MAP THIS. I only see the MAP THIS GPS EDITION and not Deniskas MAP THIS application as shown on the video.

Edit* Nevermind. I found out what I had done wrong.*

I am using PSP-290. It's showing that I am locking into 4 satellites. However, the map doesn't pinpoint my exact location. I don't get the green bars on the bottom, only red bars. What am I doing wrong?

For starters go outside when hunting for sats

Second the exactness depends on the maps you generated, some mapservices are more presice than Google maps, i have some problems with this too depending on where i am *Lol*
I googlemapped my maps too *Lol*

1. Do you have a Ta-082 PSP?
2. What GPS unit do you use ? a PSP-290 or a Holux or other??
3. What firmware are you running on your PSP "Custom 3.52 M33-4?"
4. If you use a PSP-290 did you extract your own .prx files by following my guides

5. What version of MapThis are you running v0.5 ?

Upgrade to Custom 3-52 M33-4 and extraxt those .prx files instead using my guides.
Install the MapThis v0.5

Basically youre running stonhendge-aged software

HI
At last the PSP-290 its working on my PSP SLIM

Thanks for this great software.

I woud like to report two bugs:

The altimeter its not working ok bacause when im not moving the altitude gives me diferent readings and never stop, for EX: it reads 35meters and 30 seconds after it reads 55meters.

The other bug its the speedmeter, without moving i get readings from 0,5km/h to 1,2 km/h.

Here in my position i could get 12 satellites, but not all of them get fixed, i think its normal.

Thanks a lot for this amazing software.

Well, what you are reading are probably the so-called "navigation errors" of the GPS receiver (working with one frequency only) and not bugs of MapThis!. Basically you got a navigation solution from your receiver each second: since it is a measurement process it contains an error whose order of magnitude can be several meters from time to time, especially in vertical (=altitude), depending on several factors...

For the velocity: an error of 1 km/h means an error of ~ 0.27 m/s. This is the "absolute value" of the error.
If you had access to the error components (on lat, long, lat) and you take an average over some long time your average velocity would be zero.
This is also within the performance of the GPS receiver for a velocity solution therefore...

... everything seems fine with your navigation set-up!!

Bye,
