Heya folks,

While I was rummaging around in the rear driver's side compartment of my car, I found a unit that has what appears to be a GPS antenna attached to it.

My car doesn't have a nav system, but this antenna is there. When I scroll through the computer on the dash, it says "Arrival Time". Is this normal? Does this means I can more easily retrofit a nav system?

My stereo component is full of dead pixels, so I have a hard time using it at all; if I can easily (and economically) retrofit a nav system, I'd rather do that.

Thoughts?

Thanks!
