Novice question

Hello all.

I am totally novice to this and I would appreciate some help.

I was given a gps system which has an 'igo primo' navigation software installed, and it seems to me that its OS is WinCE. I would like to upgrade the software and/or include recent maps for Turkey and Europe. Can anyone tell me how to start? I see so many different versions of software here and I am confused.

The device I am using is clearly a chinese device, which claims to be a 'Pioneer'.

Thank you
