Prius V GPS - HELP! (Newbie)

Hey guys,

Just got myself a Prius V a week ago and am trying to figure out how to activate the GPS for JBL Head Unit (since it did not come pre-installed, and from what I understand the JBL Units are GPS capable). Asked around (as in Kuala Lumpur, Malaysia) about hacking but no one seems to be able to give me a straight answer.

So my question is:
1) How can we tell if the JBL Head Unit is GPS capable (so I can prove it to the workshops)
2) If it is capable what do I need to do to get it activated? (I heard it uses Garmin, but in Malaysia garmin doesn't sell original SD cards).

Cheers Guys
