Usually the program will offer the update itself. I found a 2.8 cab update from Telenav, but it didnt list the Touch Pro 2 as a compatible device. Only the Touch pro. I downloaded it and ran it on mine figuring their not too much different.
It took a couple attempts to get it started, but on the third try it finally booted up and logged in. When it loads, the main menu at the top says "Sprint Navigation Lite".
Ive attached it to this message if you want to give it a try. GL
