Mazda CX7
I need a GPS antenna for my CX7 which (as far as I know) has the part number 66-DY0. I have being looking in eBay, etc. and I found out a lot of GPS antennas with part number ending in 66-DY0 but different first 4 letters. In example, EG23-66-DY0, FE50-66-DY0, BBM2-66-DY0.

My questions are:
1. Can I use any? At the end of the day is just a GPS antenna which they all must do the same thing.
2. Are their part numbers different because they have a different metallic base that fit in a particular Mazda model but the antenna itself is the same?

Thanks a lot for your answers.
