Since the SCC1 is very hard to find and expensive we have an alternative for many customers here.
The SIRIUS SCC1 SiriusConnect Universal Vehicle tuner allows you to add SIRIUS to many aftermarket & OEM radios. Most installations will require an Interface/Translator or a special Interface Cable. In rare cases, some radios do not need either and will connect directly to the SCC1. The SIRIUS SCC1 Tuner supports all programming packages currently available on the SIRIUS network, including “SIRIUS Premier (The Best of XM)” package.
