GPS with google or/and WiFi

Hello

Is there a GPS unit out there that I can send my address/routes to VIA my home computer to the unit sitting in the car?
Like sending the info VIA WiFi or some sort of google transfer?

I know the new BMW cars let you pick your route on your home computer, and when you get into your car, the GPS unit in the BMW's have the address/ route

Any Ideas?

I am not sure if there are dedicated car GPS units with Wi-Fi however there are units that have bluetooth and can be paired up with a cellphone. I have seen some after market all in one units (Dvd, GPS, radio, etc.) with wifi while surfing. I have also seen Android based units as well. I know there are portable hand helds that do have wifi but since cell phones usually come with GPS now most people use them.
Google would be your best option searching one out.

Magellan has what they call a smart GPS It will work with your smart phone They are about $160
I would think the others would too
