Anyone know a way to change the TTL this unit uses. I have tried TTL master and it says im 65 but im still slowed with wifi teather from my Iphone. I did test with my laptop off wifi teather and it was full speed so not a iphone wifi teather issue. Yes I installed a kernal that allows root access but not sure why this works with windows computer to my iphone but this headunit shows set to 65 been rebooted still shows 65 but still slow on speed test. Btw it is fine speed wise connected to my house wifi but just wanted faster speeds in the car when on the road.
