Lihan FM Transmitter 3-in-1 Adapter
If you want to upgrade your rust-bucket as I did on my spare 1994 Toyota Pickup, get the Lihan 3-in-1 FM Transmitter.
This thing plugs into your cigarette lighter and transforms the interior into the 21st century. You get a Bluetooth FM Transmitter so you can make calls and play music from your phone on the stereo inside your car. Then, there are two USB ports for regular and fast charging, not to mention a digital clock.
And finally, this adapter has a 1-click call answer button that lights up, and easy music controls that pairs over BT and works with your phone. It's a "do it all" smartphone car accessory. You're welcome.
