Some years ago I updated the radio in my 2001 330ci to the newest E46 Business model with satellite mode. I put the receiver (?) in the trunk and the antennae in top part of back seat. I had it working for a few years (with subscription) until I put the car in storage for several years (canceled subscription). I have the car back on road and the radio shows sirius on channel 1 in the mode but no sound. The refresh requires a subscription. Is this the way its done now? I thought channel 1 was free. Is something wrong with my setup? I listen quite a bit to free Pandora and wondering the best way to go for music. My new Iphone does not have the aux connection so installing that would not help. Any suggestions? I paid a lot for this radio upgrade and I like the look. I know Dynavin is an option but its pricey and requires a bit of technical expertise. Thanks for any help.
