GPS booster for cars?

[rodion15]

I heard in a TechGuy podcast there's some device to make your smartphone GPS more precise while driving.
You put on your car and attach antennas somehow and connect it to your smartphone with an app or something and Google Maps will be incredibly fast and precise while driving, without those lags when you're approaching a bend.

Anyone has heard about this?

Thanks in advance
