hi everyone. i got obd2 cable from ebay and i managed to install inpa and dis. the thing is inpa works fine but i cant get dis to work. i have 2 green lines at the top saying its pared and signal is good but when i connect to the car it say it cant communicate with a diaghead. the thing is that i spent so many hours trying to get it to work that i lost all the hope now. i was wondering if anyone in here is from Somerset uk. that can give me a hand with installation.
