With this entry I want to clarify the radio installation kit that have been installed and can be installed on your RAV4. And so on in order.
1. Native head unit Toyota 86120-42220, put on pre-styling, disks, radio, in general, nothing interesting can be said about it. To play music from a flash drive, there are options for special adapters such as Yatour, Chinese kits, FM modulators.
2. Toyota 86120-42280, all of the above, just modified. If I'm not mistaken she still has AUX.
3. Toyota B9017. Here it is already more interesting. First, a screen appears. There is a standard Toyota navigation, with the possibility of updating (in great detail about the update is discussed on the Prius forum), it is stored on the hard disk, there is the possibility of connecting a reversing camera (and it is not necessary to tell that this is impossible). The USB input did not appear (again, adapters). There is AUX. Since the 2009 model year, the connector has been changed to FM, it has become a square Toyota. 
4. Kit Toyota B9004 (for Europe) and B9022 (for Korea). Similar to the B9017, slightly different buttons, inside the filling of the previous generation. Navigation is stored here on DVD. AUX and USB stick are missing.
5. of the latest head units Toyota RAV 4 2020 android with a navigator, a rear view camera and a touch screen are represented by the brands Redpower, Cardrox, Carmedia, FarCar, Roximo, Daystar, etc. 2 din car radios are made on the Android 8 system | 9 | 10, YouTube, Navigator with Alice, online TV, online radio and other useful applications with GooglePlay.

If the signal is weak, if the automatic search does not fix the setting, press the tuning button again (automatic search is disabled) and tune manually one step at a time. During stereo reception, the “ST” indicator lights up on the display.

You can memorize your favorite radio stations. To do this, tune to the desired radio station, then press and hold one of the buttons (5-10) until a beep appears. Switching to the tuned radio station is carried out by briefly pressing the desired button.
Note:
in case of prolonged absence of batteries, the radio tape recorder memory is erased and the factory settings are set.

Pressing the “TUNE” button (3) plays the selected track in order. Pressing the button again plays the next record.
"Favorite radio station"
You can tune the most frequently listened radio station to a separate button (13). When you press this button, the selected station is immediately turned on, regardless of what device was working before.
Note:
on the new radio tape recorders, a wave of 1620 kHz is tuned.

Note: During reception of a traffic announcement radio station, the tuning and station selection buttons are disabled. First, you need to turn off the reception by pressing the button (13) again.
The full performance of the Android system will be available if the Internet is available. It is implemented using wireless Internet distribution from the phone or a modem is purchased in addition, where a SIM card is inserted. In this case, the navigation unit on Android will work independently of the phone.
An Internet browser will allow us to go online to read news, mail, enter search queries, and so on. The navigation block has a full-fledged store for downloading applications. Most Android apps on Toyota RAV4 are free. This makes the Android platform attractive compared to the inconvenient and highly limited functionality of CarPlay or MirrorLink.
And even a modern head unit is equipped with a radio kit for TOYOTA RAV4.
