Ok, I finally got this to work after months and months. i will detail instructions
Iphone 3gs 3.1.2 Jailbroken( I have a 3gS but the 3G will work as well)
Sling player at home
mobile sling on your I
3g unrestrictor to enable streaming over 3g
TVout Tuner from ROCK
(Other TV out App must be deleted...doesn't work anyway)
Set up 3g Unrestrictor to allow access for SLING
On UNIT(AVIC) go to Movies> then select a movie.
Once its playing on screen hit the home button on your I. ( Don't touch the UNIT)
Enable TVout Tuner, once this is done it will show the springboard on your UNIT.
You can play any game or use any app. You will have to mess with the screen rotation in TVout Tuner as some apps act differently.
Start Sling and enjoy, if your 3g connections is good enough..watch the football game or whatever.
See screenies....
I cant or wont help with how to jailbreak. If you have a SMART question yell. And maybe I can help.
Good Day...420
This is the real deal if you don't believe me then...you know
