We've had satellite radio for several years. We do long car trips and live in areas with little or no reasonable(our opinion) radio service and it has been a godsend.

We installed XM in one car and on that first trip drove from South Texas to New England and never were with out the radio.

Sirius came in another car and is fine. My husband prefers XM. I don't care.

We tend to listen to news/financial stuff with some Broadway/big band music but there are lots of choices.

If you live near a major city (I think you do), it probably isn't a necessity.

We bought the first one at Circuit City (they installed it) and the second one came installed in the new car. I don't think this is a do it yourself deal.

Hope this helps . . .
