With many carmakers already offering satellite radio capability on selected models, it seems only a matter of time before it is a universal standard feature. Even though most car manufacturers include a specified number of months of free service -- for example, GM offers 12 months -- you will have to pay a subscription fee at some point.
At XM Satellite Radio, subscriptions begin at about $10 per month. But with the vast selection of music, entertainment and information offered by XM and Sirius Satellite Radio, the cost is reasonable. For anyone who spends hours a day commuting or traveling long distances by car, the crystal-clear reception and signal availability are probably worth the price.
