Hi, I purchased a Sirius XM Radio SXV 200 tuner kit from Best Buy for about $50.00. The tuner plugs into the Magnadyne. You have to use the u shaped tool, that should have come with radio instructions, to get the radio out of the dash and route the antenna to the tuner. I put the antenna on the front fender and painted it to match the color. If you don't mind paying a few bucks Best Buy will install for you. Of course once it is installed you just call Sirius and they will hook you up for a free trial period and offer you a subscription deal. We are country music fans and recently made a trip through California, Arizona and Nevada we never lost the signal and enjoyed virtually commercial free radio for the entire time. I hope this helps.
