You don’t have to attend CES, with its auto company CEO keynotes and tricked-out show cars, to realize car tech is a huge industry.

I recently looked at the latest in affordable, aftermarket car tech for a Money magazine story. During road trips in Vancouver and Chicago, I tested multiple GPS systems, Bluetooth speakerphones and in-car cellphone chargers as well as one tablet-like gizmo that streams music and pulls data from iPhones. I also sifted through the wide, wide universe of car-related mobile apps before choosing a few to feature in the story.

A version of the article, which appears in Money’s November issue, can be found here. (If you’re interested, check out the piece in print; the layout is fun. Part of it can seen above.)
