They make the erroneous 15 mA assertion, in my opinion

Atoto F7 vs S8 There are two variances (and the product description includes a guide pointing this out). The XE supports wired Android Auto or CarPlay, charging while connected via USB, and SiriusXM. The WE supports wireless AA and Carplay, so the charging issue isn't too important (you can use any other generic phone charger if necessary). The charge port should still work. Whether or not you need SiriusXM is the crucial question. Additionally, the XE is less expensive than the WE according to Amazon prices, so in my opinion it is worthwhile to get the XE.  I do indeed own an A6, and 600 mA is a substantial drain. They make the erroneous 15 mA assertion, in my opinion. I can only go a few days without a dead battery, so I'm considering cutting off my direct battery lead. The most recent S8 series has not yet been tested by me.   I have also noticed this. I disconnected my phone from CarPlay, and as a result, the hourly time intervals are now around one minute long. It really irritates me.

The most recent S8 series has not yet been tested by me.  All F7 versions, starting with the F7G2, are aftermarket, all-din double-din car stereos. The universal car radio can be installed in any car as long as there is enough room for it to do so and there are compatible installation kits (such as a dash kit, wire harness, or CANBUS data interface) to assist with the process. You can start by searching for installation kits on websites like www.metraonline.com, https://www.crutchfield.com, or https://pac-audio.com; just enter some information about your vehicle, and the website will suggest installation kits. Please refer to the advertisement's final image for a list of the extras that come with the vehicle radio. 

The S8G2A78UL-N is a double-din universal aftermarket car radio; if your car can accommodate double-dins or if a double-din dash kit, wiring harness, or CANBUS data interface is available to complete the installation, then any automobile, including yours, will be able to use it.  Our universal radio, model number F7G2A7SE, can fit any car, including yours, if it supports double/single dins or if the necessary double/single din dash kits, wiring harnesses, or CANBUS data interfaces are available to complete the installation. You might need to acquire additional mounting gear in order to attach the radio.  It is, indeed. One that allows you to download maps to be stored locally or offline just needs to be installed. The built-in GoogleMaps app has this functionality, but it's a pain because it's a Google product and the app will periodically delete (or expire) your downloaded maps, forcing you to connect to the internet to download updated maps that are rarely any different from the previous ones, unless new roads have been added since the last downloads. 

Important Features of F7 XE 4*49W maximum and 4*29W RMS amplifiers built-in. With the aid of a 10-band EQ with 7 presets, timing correction, and bass filter capabilities, you may enjoy an aural feast. For hands-free calling and music streaming, Bluetooth 5.0 supports HFP, HSP, A2DP/AVRCP, and PBAP. GPS on the internet: You can utilize iOS Maps or Google Maps/Waze on the HD screen of the F7 with a custom hardware solution to link CarPlay or Android Auto as long as they are accessible on your phone. The 2-RCA headrest video outputs, 4-CH RCA audio out (4 volts), and separate subwoofer out (3 volts full range) outputs can all be linked to an OEM or aftermarket amplifier. Included are an HD display, two USB connections, and one SD card slot. HD A true 7-inch 1024 x 600 QLED touch screen with superb sensitivity and a 178° full viewing angle may offer you a fantastic screen-watching experience even in well-lit surroundings. On the screen, navigating in HD is possible. Thanks to dual Bluetooth processors, the S8 can connect to several phones and other Bluetooth devices at once. The BLE connection and Bluetooth tethering network are supported by BT2. The BT1 comes equipped with Qualcomm's aptX HD codec, allowing for 24-bit audio quality over BT and enabling the ability to hear even the slightest melodic details (the phone must have the BT aptX HD codec). Both cable and wireless CarPlay as well as Android Auto are supported by the inbuilt phone integration link. Use the TrackHU GPS tracking app from ATOTO, which is installed in your car's radio, for real-time tracking with a 15-second refresh rate, OsmAnd's four satellite location, track replay with speed control, full reports, and instant online/offline status and geofence alarms. You may easily keep an eye on your car, regardless of whether you've lent it to a friend or family member or it was sadly stolen. It offers a quick method for keeping an eye on the path and ensuring the safety of your car. The S8 (Gen 2) is the second iteration of the ATOTO S8 Android car stereo. Its SoC uses an ARM Cortex Octa-Core processor (high performance), a 12nm manufacturing process (greater efficiency, lower consumption), and the most latest ATOTO AICE UI 11.0 (deep customization on Android Q). The brand-new ATOTO S8 can increase comfort and assurance across a range of treatments. Wi-Fi hotspots, Bluetooth, and USB tethering are the three alternatives available for internet access (traditional Android car stereos only have the Wi-Fi option).
