Hi Guys.
Thanks very much for all your help.... unfortunately no joy here. Followed the above instructions and all I had happen was that the lights went out! Still not recognised by my system. Incase your wondering, I did try it on another box with out success...... Have emailed TM to see what they can come up with. Curious side issue. To make sure I got it right, I tried the AP button on the throttle as opposed to the ap dis/eng button on the throttle base. This combo brought the post lights back on.... Still no joy.
Happy New Years!!
