AutoTrends has the car electronics you need, from 12V adapters to FM transmitters.
What Bluetooth® devices can I use with my older model vehicle?
There are plenty of Bluetooth® devices you can use with a 12V charger outlet such as handsfree earphones or an FM transmitter.
Does a 12V car charger work when the car is off?
It depends on your vehicle. Most cars shut off the 12V receptacle/cigarette lighter socket when the ignition key is off. In cases like this, it won’t work.
If your car keeps power flowing to the receptacle without ignition turned on, it will work. Use this feature sparingly with charging cables. Over time, it will run down your car battery.
