Hello everyone, this is my first post here, sorry if this question has been answered or if I'm posting in the wrong section or something. Recently I've taken to 'collecting' satellite radios, but I dont really know how they work. From what I've read it seems that the newer radios (SiriusXM) use the XM satellites. So do the older Sirius radios now use the XM satellites as well, or are they still using their original satellites? Also, I saw another post here about Sirius service ending in 2022. I believe this answers my above question, but I was wondering if someone could expand on this? My radios so far are Sirius Stiletto SL10, Stiletto SL100, and two SXM Onyx Plus, and an Onyx EZ. I was considering purchasing a stiletto 2 and an Xmp3i but after seeing the other post I'm worried that the stiletto 2 will stop working in 4 years. The radios are more for collection than for actual use, but I don't really want them if I don't at least have the option to activate and use them if I wanted. Any input would be much appreciated!
