Does anyone know the location of the GPS receiver or antenna?
I'm only getting signals from 4 satellites. An MDX with nav side by side gets 8 satellites. MDX receiver is on the front windshield. Where is it on the TSX?

 

I don't remember but I think it's near the rear speakers. 4 Satellites should be fine. The manual says you need at least 3 to pin point your position.

 

3 to pinpoint latitude + longitude, 4 to get elevation, but elevation is inaccurate in civilian GPS anyway.

 

It is on the rear dash Between the 6x9s on the passanger side. If you lift the cover you should be able to see it.
