In my opinion, if you like Sirius, and plan to listen to it a lot, I would get a plug and play, and several docks, so you can move it around with you, to different vehicles and such. I have two vehicles with in dash Sirius/XM radios, the one in the Dodge was shut off a couple of years ago, and the one in the Chevy will not be renewed when the free trial runs out in June. I have two separate Starmate 5 Sirius plug n play radios, and I have docks in the house, garage, camper, 2 vehicles, soon to be three, the camper, my vehicle at work, and I have two Sirius boomboxes that will play them also (one will set on my golf cart so I can have Sirius there also). One radio is mine and the other is my wife's, so we pay for two subscriptions (second is half price) and we can listen to either of the two radios where ever we are at, and it doesn't matter which vehicle we are in, they both plug into all the docks. Just a thought.
