Thanks for the reply,
I do have the telephone option on screen, but selecting it does nothing, I dont get activate phone and it evetually goes grey and wont allow it itself to be selected.

( I believe this is the car cacthing up with me removing the motorola box and fitting the ULF).
I'll get the ulf to antenna lead and see what happens, but I wouldnt have thought this would stop the 'activate screen' appearing if all was well with the ULF, as it only looks like a length of co-ax????

Any thoughts?
