The Radio Information Board

I have a customer that is interested in adding an AVL system to his 2-way radios. I've done a little research, and found some gear offered by Pyramid, CES, and RadioTrac.
I was wondering if anyone has had any experience and/or recommendations for AVL systems.
BTW, they are going in Motorola radios! CDM-1550-LS & GM-300's

Thanks to all in advance.

the CES stuff is nice and can be supplied through M to be plug & play....Z

I thank you for your response.
We got a demo kit thru /\/\ and set it up. Works well.
I think we made a sale. (I hope!)
Thanks again!
