Smartphones have pretty much taken over as the default navigation tool for many drivers. However, some locales (including our home state of California) have outright banned smartphone use in the car: no windshield mounts, no dashboard cradles. So, how are you going to get your turn-by-turn directions when looking at your phone is illegal?

What's your phone got to do with this? HUD's data is provided by one of Garmin's navigation apps -- either Navigon or StreetPilot -- on an Android, iPhone, or Windows Phone 8 smartphone.

So you still have to own (and use) your separate smartphone to power this new gadget. So what problem is it that they claim to have solved? If you can't use your smartphone per state law, what good is a projector hooked to your smartphone?

It's a cool high tech gadget. However, I predict a gadget of limited useability, usefullness, and need. But most of the electronic junk we buy these days is unneeded and not very useful anyway, so I guess this is no different. It's kind of an "electronic jewelry". No real need for it, other than the "please notice me in the crowd" bling-bling effect.
