Hi, I'm new to the whole scene and I could use a couple of pointers. I'm interested in getting one of these things for:

-Playing Mp3s
-Watching DVDs
-Some (not too graphic) games
-GPS

I live in Uruguay and I was wondering if the GPS will work here and if there are any maps available for the country.

What's right for me? What system do I neeed?

I have an old JVC MP3 stereo with an input jack, however when I tried connecting my MP3 Player Pen Drive to it it wouldn't work. Any suggestions? Will I need to buy a new head unit?

Well, I'd like to make a choice soon so any help is appreciated.

Regards,
D.
