You’d be amazed at how many companies want to pipe commercial-free entertainment into your car for a reasonable monthly fee. At the annual Consumer Electronics Show in Las Vegas, the place was crawling with them.

You already know about the two satellite radio providers, Sirius and XM. Sirius just hit the 3 million mark in subscribers and XM 6 million. The ways you can listen to satellite radio also grew.

Sirius launched its own S50 portable player about the size of a Snickers bar that clicks into in a car or home docking port to receive satellite entertainment and also stores up to 50 hours of music, including MP3, for portable listening. With the car kit it is $329.99 (there is a $50 rebate on Sirius’ website). The home dock is available separately for $99.99.

XM touted new handheld portables, too, the Samsung Helix and Pioneer Inno, both $399.99. They can play live XM radio or MP3 files in portable mode and can even browse and purchase Napster music. A home dock is included. The Samsung Nexus stores either 25 or 50 hours of entertainment for $199 or $249 respectively. The Nexus comes with a car kit, while a home kit costs $29.99. If all you want is XM radio, the XM Passport tuner connects to a home stereo, car radio or even clock radio to play XM on a wide variety of electronics for just $29.99. Home and car docking stations are another $29.99. The Passport will be available in spring.

Then there’s HD Radio, from iBiquity. An HD Radio digitizes the existing analog radio signal you are already listening to in your car. The advantage, in addition to greatly improved sound quality, is that your favorite radio station can actually broadcast another channel or even two other channels on the same frequency, which can then be picked up and played only by an HD radio. So KPIG could broadcast country, classical and news and you could listen to any of them on your HD radio. HD can also send traffic data, song IDs and funny jokes that crawl across the part of your radio that usually just says “KPIG 94.9 FM.” BMW already has HD radios in its 6- and 7-series cars and will launch 3- and 5-Series HD radios soon. Right now there are about 650 digital radio broadcasters in America (3000 are committed by next year, says iBiquity), 80 of which are multicasting. HD receivers range from $300 up to $800 or so. There were numerous HD Radios on display at CES. www.ibiquity.com.

Motorola iRadio is a radio subscription service ($7 to $10 a month) that allows you to download any six of 435 channels of commercial-free music to your ROKR E2 Motorola phone ($300), which holds 10 hours of programming, either iRadio or songs from your iPod. The phone then plays any or all of those 10 hours via Bluetooth on your car stereo. Recharge your phone and you can change the mix. There are now more than a couple million songs available, including everything from rock to “Ancient Music,” which gives you all the greatest hits of the Dark Ages. Even millions of songs isn’t enough. Said Motorola’s David Ulmer, “My mission is all music known to man.” www.motorola.com/iradio.

But that’s all just radio—how about TV? RaySat unveiled its SpeedRay 3000 system, which offers in-motion satellite TV as well as high-speed internet access. It will be out in the third quarter of this year priced a $6995 plus a monthly service charge of $50 to $100. If you can’t wait that long you can get the SpeedRay 1000 right now, minus the internet. www.raysat.com.

KVH, which has made satellite TV systems for mobile applications, including cars, since 1996, announced a new automotive internet service at CES. Through a partnership with Microsoft MSN TV the system uses land-based cell service available in 170 metro areas to pump TV and the web into your vehicle. It is expected to debut this summer priced at under $1000 plus a monthly subscription. www.kvh.com

There was much more at the Las Vegas convention center than we can get into here, including another aftermarket product that offers real-time traffic on a nav screen (the Kenwood KNA G510), zillions of Bluetooth-enabled mobile phone conversions for hands-free driving, more TV screens in the backs of more car headrests than you could shake a remote at and, our favorite, an improved Ride Tones programmer so you can make up to eight functions in your car that used to just chirp make almost any noise you want them to make (www.ridetones.com).

Ain’t life grand?
