Can someone confirm the radio that I have in my Equinox? It is a 2010 without the large screen navigation display. I have attached a picture of the radio. I am looking for the correct part number to the plastic antenna base on the back of the car. I need to replace it and found that there are several options dependent on the radio you have. We have Onstar and XM radio on this unit. There are 2 different antenna bases that I think I am down to. #'s 20863980 & 20863981, but am not certain if it is one of those numbers.
Thanks,
