We've definitely proven that there's a little juice left in a cassette deck tank and this product further revives that concept. This is the Bluetooth Cassette Adapter by Flexii. This isn't Bluetooth of the cell phone communication nature, but rather Bluetooth of the AD2P streaming music nature. If your cell or MP3 player is capable of streaming music over Bluetooth then this could be a great addition to your seemingly outdated vehicle.
It is rechargeable, so there are no wires hanging out of the deck and it will connect wirelessly with an MP3 player to stream music through your vehicle's sound system. The rechargeable battery will last around five hours. You can now rest assured that your vehicle is just as capable as the new age Sync contraption. It's available for $40, so no need to rush out and get a Focus. [Slashgear]
