Remote control
The presence
of a remote control in the scope of delivery of the FM transmitter.
The ability to control the device from a distance is convenient, first of all, for passengers in the rear seats — for the driver,
the remote control on the steering wheel is more relevant (see below), and the “navigator” in the front seat can easily reach the transmitter itself.
Max. memory card / flash drive capacity
The maximum size of a memory card or USB-drive (flash drive) supported by the transmitter.
For more information about memory cards and flash drives, see "Cart Reader" and "USB Input", respectively. Here we note that a modern FM transmitter can support two types of media at once; in such cases, the volume limit is often relevant for both flash drives and memory cards, but this nuance does not hurt to further clarify the documentation. Anyway, this limitation is primarily due to the fact that a higher storage capacity requires a more powerful hardware; in addition, there are nuances associated with individual subspecies of memory cards. Anyway, it is impossible to exceed the maximum allowable volume — this can lead to malfunctions and even to hardware breakdowns.
Media support
File formats supported by the FM transmitter.
Almost all models support the MP3 format, which is the most common modern digital audio format. Some devices are also capable of working with WMA — this is also one of the main formats, but for a number of reasons it is used much less often. And even less common is compatibility with WAV — this format provides higher sound quality, but with FM broadcasting this advantage is lost, and the files themselves take up noticeably more space than MP3 and WMA.
Flexible neck
The ability
to change the angle at which the transmitter housing is located relative to the cigarette lighter socket. This function is realized thanks to the swivel plug for the cigarette lighter. It allows you to choose the most optimal position of the device for a specific situation — for example, raise the transmitter if it prevents you from reaching the tray under the cigarette lighter.
