Pandora (News - Alert), the Internet radio service giant that allows users to create custom Web radio stations based on old and current favorites, is adding on to its platforms.

The company just announced partnerships with 23 car manufacturers, rising from its previous number of four. Users can expect a Pandora system in just about every new car sold now.

With 125 million registered users, it has 68 percent of the Internet radio market. Its users listen to an average of 18 hours of music per month.

Ford, Honda (News - Alert) and Subaru all announced partnerships with Internet radio providers at CES (News - Alert) this week, promising digital and custom user-created radio stations and other Web content to be integrated into their vehicles by leveraging the user’s smartphone and a free downloadable app.

Honda and Subaru plan to offer Aha radio, and Subaru says Aha will provide access to tens of thousands of stations, including on-demand music from Pandora competitor MOG and Rhapsody; Internet radio from Shoutcast, CBS and Slacker; live news; podcasts from NPR and others; free audio books; personalized traffic reports; Facebook and Twitter newsfeeds; and user restaurant reviews and recommendations from Yelp (News - Alert).

Cars to look out for include BMW, Mini, Buick, Cadillac, Chevrolet, GMC, Acura, Honda, Hyundai, Kia, Ford, Lincoln, Mercedes-Benz, Lexus, Toyota, and Scion. Pandora will be embedded in cars using voice commands or dashboard controls.

In related news, Viper introduced Viper SmartStart 3.0, the cloud-connected car, at CES this week. Viper SmartStart was the first app that allows users to affordably start, lock, unlock, locate and monitor their vehicle – all using their smartphone.

The new features include SmartSchedule, where users tell SmartStart their daily routine and the Directed Cloud Services (DCS) network does the rest. DCS will continuously monitor temperature, location and schedule variables in the cloud and push smart alerts to their phone when it’s time to warm up their car.
