The holy grail for me is a cellular enabled nav unit that runs google maps as it source. I'd pay out the nose for it.

 

Check out Mapquest.com

They support direct uploads to your Garmin (route planning if it's a 700+ series, otherwise it's just a list of the waypoints). The site also supports cell phones and Onstar units - not sure which ones specifically though.

 

I've got a 250. No waypoints for me. I just want to be able to type in and go.

 

To revive an old thread. I found a website that provide a tonne of icons for Garmin, and one of them has a red Honda S2K.

Then click on Sports car - you'll find the S2K there.
