Some cars have too much "stuff," and it doesn't always work well.

Hypersensitive electronic sensors, rear view navigation systems with blurry visual quality and inefficient braking systems all come to mind.

Yet, two items standout among as the best of the worthwhile technology wonderment.

Neither is likely to impress engineering wizards or car buffs. But I think every car would be better if it featured satellite radio and a voice-command navigation system.

One of my recent weekly test drives, a 2007 Chevrolet HHR, offered both features. The retro wagon's appearance, styled after the 1950s Chevrolet Suburban, attracted attention. But the car's exterior color, "sunburst metallic orange" garnered even more stares and comments.

But what I liked about the car most is that it featured XM satellite radio and the new OnStar "turn-by-turn navigation system.

Satellite radio is available on an increasing number of vehicles, and for me it's now a disappointment when it's not available. The vast music, news and sports channels are ideal for long drives. And satellite radio is an ideal way to eliminate the annoyance of commercial overload on AM/FM channels.

The new OnStar system, available on select 2006 General Motors' cars and most 2007 editions, features both a digital display and voice command for directions.

During my week with the HHR, the OnStar system, called "Turn-By-Turn Navigation," worked well. Its ease-of-use functionality was impressive, even for someone who appreciates the motto: "The fewer the gadgets, the better."

Generally, the system worked well and the advisors I spoke with were prompt and professional.

Of course, XM satellite and the OnStar systems are not free. In my HHR, the one-year OnStar "Safe & Sound was priced at $695 and the XM radio option was $199 for a year with an additional three free months.

Nevertheless, for a car buyer considering option packages, XM satellite radio and the new OnStar system warrant serious attention.
