Griffin SmartTalk Solar Bluetooth Speaker Kit

Some cars today have hands-free Bluetooth smartphone capability built in, such that calls automatically come in over your car’s speaker system and a built-in microphone picks up your end of the conversation.

If you don’t have a car with that feature, you may want to consider the Griffin SmartTalk Solar, which is a small Bluetooth speaker in a case that attaches to your windshield with suction cups.

It has a built-in solar panel to keep the internal battery charged.
