Question about Enhanced 911

I can't get my Motorola L7 to work but maybe I'm missing something. Do I need an external GPS device? Or is the built in GPS for Enhanced 911 sufficient. I've heard that only Nextel, certain Blackberry's and Boost Mobile allow third party software to access this functionallity. Is this true? Or should I be able to just run the software and at least get my lat/long? Thanks in advance.

hi, I don't know enhanced 911, but I think you will need a external bluetooth gps receiver.
