Hi,
I am trying to upgrade my trip computer to gain the extra features.
I have installed the new indicator arm and I have installed the new trip computer/speedo.

I can scroll trough all the menus etc but i cant start the engine! do i have to have to add anything else like an exterior temp sensor? ( i cant see why not having the exterior sensor would stop the engine from starting)

Looking forward for any help,
Thanks in advance,
Mohit Gadhok
