1DIN size car radios - the exact dimensions including the metal frame where the car radio is inserted are 184 x 53 mm, the external dimensions of the branded 1DIN car radio are 188 x 59 mm.

We know 2DIN car radios from newer vehicles, a classic example is the VW Golf IV with navigation. The dimensions of a 2DIN car radio without a metal frame are 180 x 101 mm, the external dimensions of a branded 2DIN car radio are 189 x 119 mm.
1DIN
Supported formats via USB inputList of all supported formats (MP3, AAC, Flac, DivX, etc.) that the car radio can play via USB input. FLAC / MP3 / WMA / AAC / MP4
USB inputThe USB input of the car radio is used to connect a USB flash drive or smartphone. Today, playing music via USB is the most popular way to listen to music in the car. The USB input can be front (on the front panel of the car radio) or rear (on the back of the cable). Yes

Integrated BluetoothBluetooth is a communication technology used for wireless connection between two or more electronic devices. A mobile phone, for example, can be connected to a car radio with built-in Bluetooth. Most car radios for 2017 and later can also wirelessly stream (play) music via Bluetooth -> A2DP function. Yes
Audio Streaming via BluetoothA2DP (Advanced Audio Distribution Profile) is a Bluetooth profile that enables the wireless transmission of stereo audio from an A2DP source, typically a mobile phone or computer, to an A2DP receiver (car radio). These devices usually also support the AVRCP profile. Yes
External microphone included in the packageThe external microphone is connected from the back of the car radio to the input marked "MIC". For ideal sound quality during a phone call, we recommend placing the external microphone on the left "A" pillar at the point where the "A" pillar and the roof panel connect to each other. A very good position to place an external microphone is also near the central rear-view mirror. Yes
Number of RCA outputsRCA outputs , colloquially called "cinches", are used to connect an external amplifier or active subwoofer. Aftermarket car radios are usually equipped with 1 to 3 pairs of RCA outputs. FRONT, REAR and SUB are used.

It also depends on how many volt outputs the car radio is equipped with. More basic models of car radios have 2V outputs, more expensive units have 4V and more. The higher the specified value, the less power demands are placed on the external amplifier and the sound quality increases.
3 pairs
Output level on RCAAn important parameter if you are going to install an external amplifier. If you purchase a car radio with a basic value, i.e. 2V outputs, then greater demands will be placed on the power of the amplifier. As the value increases, e.g. 4V or 5V, the power of the external amplifier increases significantly, in layman's terms.

A car radio with strong outputs therefore has the advantage that you do not pull so much power through the amplifier and thus achieve a better sound, as external amplifiers lose control at higher loads.
4 V
