I think I'm missing a RAD -->TEL initiate link to handset.

I have a radio here but it won't power up unless connected to a car.

Nope.

Yes it will, when you know how :-)

I apologize if this has already been answered here or in another thread. I am currently in the market for either a ULF module or and TCU/SES combination. There are several on eBay, but most ads market them as being specific to certain models/series.

Up until this point, my understanding was that a particular ULF, TCU, or SES module would work in any car, with the limitations being age of the module relative to the car. Are these modules also model/series specific?

Also, is there any difference between a ULF Module and a ULF Module, High?

They are model specific

A ULF won't work in a 1500, 1600, 1800 or 2002
Neither will it work in an E24, E31, E34 or E36
It also won't work in an M1

But it will in many other ibus-cars....

Good to know. I understand from your's and Big Bob's message that the ULF is model specific and that the SES has no phone compatibility issues, but do the older SESs (e.g., pre-2003) have any kind of compatibility issues with respect to the car itself? In other words, if I bought a 2001 SES that was taken out of a 7-series, would it work in my 2003 M3 coupe?
