Just to clarifyIn different order...Sirius radios use different technology then XM..
Because of bandwidth constraints one has more channels than the other
The main difference between Sirius Radio and XM Radio is the platform that the radio is built on, which determines which subscription plans are available:
- Sirius Radio: The Sportster and Starmate radios are on the Sirius platform and receive Sirius plans.
- XM Radio: The Onyx and XM3pi radios are on the XM platform and receive XM plans.
- SiriusXM Radio: The Lynx and Edge radios are on the SiriusXM platform and receive SiriusXM plans.
