What is this thing in my passenger side thats ia connected to the car?

 

Looks like an antena for navi system but I'm not positive

 

I have something similar like that. But it's an antenna for the navi/satellite radio. Looks like that G has an aftermarket radio, double din unit perhaps? And that's an odd spot for the antenna since it's covering up the vent.

 

That's either a GPS or Satellite radio antenna or possibly both. That is a pretty crap place to keep it though, I have mine hidden above the clock underneath the piece of trim that pulls out.

 

They're antennas, one is for the GPS system and one is for satellite radio.
