I am planning to buy a Garmin Nuvi 750 or 760. I currently use a Streetpilot 7200 that has a traffic system from the XM network that works &quot;adequately.&quot; The newer Nuvi only gives a choice of MSN Direct or a GTM 20 FM TMC (an antenna device). Which currently appears to work better? Which has a better future? Can I expect them to work better than the XM network?

I am planning to buy a Garmin Nuvi 750 or 760. I currently use a Streetpilot 7200 that has a traffic system from the XM network that works "adequately." The newer Nuvi only gives a choice of MSN Direct or a GTM 20 FM TMC (an antenna device). Which currently appears to work better? Which has a better future? Can I expect them to work better than the XM network?

Which traffic and weather alert system is best for a GPS - the GTM FM TMC or MSN Direct?

The Global Positioning System (GPS) is a space-based global navigation satellite system (GNSS) that provides reliable location and time information in all weather and at all times and anywhere on or near the Earth when and where there is an unobstructed line of sight to four or more GPS satellites. A geographic information system (GIS) or geospatial information system is any system that captures, stores, analyzes, manages, and presents data that are linked to location(s). In the simplest terms, GIS is the merging of cartography, statistical analysis, and database technology.

GIS/GPS Programming

Microsoft applications include a variety of software programs, including development and digital authoring programs (Expression and Media Center), educational programs, Internet software, including Essentials, Skype and the Live family, anti-virus, productivity applications and suites like Office, Excel, Word, Outlook, Access and PowerPoint, video games and server applications such as Exchange, SharePoint, IIS and Virtual Server.
