The presence in the FM transmitter of special tools for
connecting Apple gadgets – primarily iPhone smartphones and iPad tablets.
Technically, such devices can also be connected via a standard AUX or Bluetooth input (see above). However, in this case, the presence of a plug for a proprietary universal connector is implied (it is also often supplemented
with a phone holder – see below). Through this connector, you can, for example, switch tracks, show service information about the operation of the transmitter on the smartphone / tablet display, and even charge the gadget's battery. Specific functionality varies by model.
Possibility of operation of the device with automobile networks with a voltage of 24 V.
Such tension is found in heavy equipment — in particular, buses and main tractors (“trucks”). By default, FM transmitters are usually made for the 12-volt on-board networks of cars; therefore, for
installation in a 24-volt network, you need to choose a model where this possibility is directly stated.
