hey, i have an alpine ixa-w404 head unit in my truck and a jailbroken iphone 4. I was wondering if there was a way that i could get my navigon app to show up on my decks screen in my truck. i have screensplitr, displayout, tvout2 already on my iphone but i cant seem to get them to work. maybe i am doing something wrong or maybe its not possible. any help would be greatly appreciated.
