Ok I know at fo people are going to tell me that the solution is already all over here but I've seen so many different ways and alot of them turn out to not fully work right so i'm going to ask and see if someone here know for sure how to do this right with no problems. How do I do the bypass on 2008 SNS system so I can input data and watch movies on the screen while the car is moving. Been reading that Toyota is really strict with this and made it complicated which is why people have had so many difficulties doing it. Whoo has done this and has been successful as far as all functions still working when doing this. Thanx.

 

navi functions will not work when bypassed. you need a switch.

 

ok how do i go about doing this and where does it need to be placed??
