XM antenna for GPS

I have a laptop running Street Atlas 2005 and would like to plug the XM/GPS antenna into my laptop. Since I do not have the navigation system, I would like to use my laptop as a replacement.

Has anyone attempted or have any knowledge on this?


Is the XM antenna the same one used for the GPS/navigation system?

Is the antenna NMEA compliant? Does it support WAAS? Not sure what these acronomys mean.

The GPS antenna in Nav RLs is in the dash and is not related to the XM antenna at all. Your posting sounds like you don't actually have a GPS unit. (Am I right?)

Your best bet with Street Atlas is to get one of the USB "mouse like" GPS units that Delorme also sells. It takes it's power from the USB port so there are no batteries to keep up with. You can just keep it looking up from the dash and it will keep a good lock.

Or, just about any GPS out there that has a NMEA compatible output with cable, can be used. I have used a Motorola, Garmin and Asin (Korean OEM) GPS units with Delorme SA for many years BN (Before NAV)

NMEA is the National Marine Electronics Association. They published the specification for the data format that is outputted from the GPS in "NMEA" mode. WAAS is a recent (5 years) addition to GPS's that allows the GPS to make better calculations of position based on error correction data broadcast from the GPS satellites themselves.

Most all consumer GPS units will spit out NMEA data these days. Most units made within the last couple of years understand and automatically use the WAAS data too.
