If you have an older car or one that just isnt tech-ed out with things like Bluetooth here's something that can turn your car into a tech lovers dream mobile.
The Motorola Roadster is a handy little device that can link with your cell phone using Bluetooth and it allows you to hear, answer or reject incoming calls and make outgoing calls...all hands free.
If you download the free app called Vlingo In Car you get even more features. When running Vlingo constantly listens to your car and when you say "Hey Vlingo" it will answer "What would you like to do?". You then say the person in your contact list you want to text and speak the message. It will translate your speech to text and send the message. If they reply, you will hear "Incoming text from, _____" and then it reads the message. So when you combine the Roadster with the app called Vlingo In Car you get COMPLETE hands free texting and calling.
The Motorola Roadster runs about $100 retail but I found it on Amazon.com for $47.
