Companies like XM Satellite Radio have taken digital broadcasting into orbit, but to follow you'll need an XM-compatible car stereo head unit like Alpine's CDA-7977. The CD tuner can also control a compatible CD changer. Four preamp outputs facilitate connection to your car's sound system, and a wireless remote is included. You'll need an outboard XM tuner module to pick up digital satellite broadcasts. The AM and FM bands are still accessible any time you want to return to the 20th century. Prices: $550; XM tuner price to be determined after XM service launch. 800-257-4631, www.alpine1.com
