PSP-290 question

Hi Guys

I have a PSP (original) and hacked firmware.
On my mem stck I have a copy of GOExplore, which appears to work. well it runs anyway.

I just received a PSP-290 GPS receiver from Hong Kong but my PSP does not see it.
GOExplore just keeps telling me to plug the damn thing in. It is plugged in dammit!

Is there a setting I'm missing or would I be better off with a different map software. I wanted to use this in my car.

does anyone have any ideas why this does not seem to switch on?:mad:

How do I download the MapThis software or is this also located on TPB web site :D
