I always like to see technology getting incorporated into everyday items. It's nice when you can find a use for the technology in something other than a desktop PC. The car manufacturer Ford is now going to incorporate Bluetooth technology into its vehicles - something that other higher-end car manufacturers have been doing so for years. Partnering with Microsoft, they're hoping to make Bluetooth something that's more popular than just higher-end cars.

Bluetooth in automobiles is generally aimed at wealthy people who can afford wireless headsets, allowing them to talk on their cell phones hands-free. However, with Microsoft's Sync program, which is what Ford is partnering with them to do, it opens up a lot more - emailing, music downloads - you can probably bet that iPod and Palm syncing is not far away.

Another great thing about Bluetooth in vehicles is that it opens up other possibilities - some that may not be thought of until much later. A Bluetooth-enabled vehicle is future-proofed. Hmm, perhaps you'll be able to view the car's diagnostics? Normally a mechanic needs a special program to retrieve the data from the car's internal computer. Bluetooth might be able to change that.

Ford is wise to partner with Microsoft; it takes the development stress off Ford, and whenever there's a new feature that they might want, they can request it from Microsoft.

Flat panel monitors embedded on the dash and other such features are in the not-too-distant future. <wild useless thought>If Bluetooth can eliminate the clutter of wires for a computer, why can't it do the same for the car? :p</wild useless thought> Of course, you may not want an operating system operating your car just yet - crashes would be inevitable, no matter which OS you chose.

Good follow-up to the ideas raised about vehicle diagnostics and to noting usefulness. The short, practical update below explains how Bluetooth-based diagnostics actually work today, what to watch for, and simple steps to keep a car and phone secure when using any in-car Bluetooth or OBD-II dongle.

Bluetooth OBD-II adapters plug into the standard diagnostic port and expose engine and sensor data to apps; many use the common ELM327 command set and speak over serial/Bluetooth. That makes reading trouble codes and live data easy, but it also means cheap or clone adapters can have buggy firmware or well-known flaws. See general background on OBD-II and ELM327 for how these devices fit the system: On-board diagnostics and ELM327.

Bluetooth in cars uses distinct profiles (hands-free, stereo audio, remote-control) and has tradeoffs between convenience and security. Follow basic precautions: pair only while parked, turn off discoverable mode after pairing, keep phone and adapter firmware updated, and avoid third-party apps that request excessive permissions. Official Bluetooth security guidance is useful background: . For broader vehicle cybersecurity context and manufacturer guidance, see NHTSA materials on vehicle cybersecurity: Vehicle cybersecurity guidance.

Quick checklist:

  • Buy a reputable adapter and read reviews; avoid cheap clones.
  • Update adapter and app firmware before use.
  • Change default PIN if the adapter allows it; disable discoverable mode when finished.
  • Pair and configure while the car is stationary.
  • Limit app permissions and uninstall apps you do not trust.
  • Remove or power down OBD dongles when not actively diagnosing.

These steps preserve the convenience wanted while reducing the real security and safety risks that come with wireless access to vehicle systems.
