REFERENCE POST #144 ABOVE for my exact Android Monitor Model and Purchase Options, as well as pre-purchase Q&A from the Vendor:
Some things to consider when installing the Android Monitor:
1. Prior to disconnecting the battery, move the passenger seat (or seat you plan to use for install) to a far forward comfortable position to keep you from having to lean forward as much. Also open glovebox.
2. The Android monitor needs GPS and the factory radio needs GPS (if vehicle equipped with factory NAV). IF your vehicle has the factory navigation option you can use the GPS splitter to split the radio GPS to the monitor **OR** leave GPS to the radio and install the provided GPS module (LVSD connection on back of monitor) somewhere in your dash near the windshield. If you don't have factory navigation, then you must install the provided GPS module.
3. If vehicle does not have middle dash speaker, then the two speaker wires in the provided Android harness are not used.
4. Install Harness - Camera +12V, Rear Camera RCA’s not used in installation if vehicle already equipped with backup camera.
5. On the back of the Android Monitor, plug in two smaller connectors first (if applicable to your application), b/c difficult to install if larger connector first installed
6. IF, once connected, audio is not picked via the factory harness, connect the Android AUX OUT to OEM AUX IN using an Aux Cable. You need at least a 4ft Aux Cable (very minimum). I recommend purchasing a better aux cable than is provided by the MFG of the monitor. See audio Methods in SOUND QUALITY post above for more info
7. If, after all connections are made, no OEM display can be seen then cycle through all CAR TYPES first to see if one works. I cycled through 9 and the ninth one worked for me. If still no display, disassemble monitor and check all monitor connectors
8. If you plan to use the Monitor's USBs, you'll likely need an 1m usb extension cable.
9. I created wiring diagrams in Visio showing oem wiring versus android wiring. PM me if you want me to email you a PDF.
10. Just a reminder that the flat black connector that connects into the OEM display is unused in the Android Monitor; tuck it away.
11. If you find the Android and OEM Monitors blank with no power and you CIC (radio) is also out, check fuse 142 (20A) in the trunk.
12. [UPDATED JAN.2021] AUTO DIMMING OPERATIONS:
Key In, Start ON, Engine OFF, Lights Off, Android Brightness Setting 100%
-Both Android and OEM Screens are same brightness
-Dimmer switch does nothing
-OEM>Settings>Control Display>Screen Brightness does nothing
Key In, Start ON, Engine OFF, Lights Off, Android Brightness Setting 0%
-Both Android and OEM Screens are same low dim output
-Dimmer switch does nothing.
-OEM>Settings>Control Display>Screen Brightness does nothing
Key In, Start ON, Engine OFF, Android Brightness Setting 100%
-Both Android and OEM Screens are bright, I turn on lights, both oem and android screens switch to a random dimmed setting
-Dimmer switch does nothing.
-OEM>Settings>Control Display>Screen Brightness does nothing
Key In, Start ON, Engine OFF, Lights Off, Android Brightness Setting 0%
-Both Android and OEM Screens are dim, I turn on lights, NO switch to a random dim setting (guessing it's at the lowest already)
-Dimmer switch does nothing.
-OEM>Settings>Control Display>Screen Brightness does nothing
The LIGHTS ON auto dim setting is dependent on the Android brightness setting, with 0% the lowest setting in the system. Another option, if more adjustment is needed, is try the CF Lumens app or equivalent. It adjusts screen brightness automatically to time of day and it may have more adjustment options to fit the needs. NOTE: As I learned from
Nyc Dito The Dimmer Switch and Control Display Screen Brightness settings don't work because the dimming wire remains with the OEM NAV connector that we tuck away once the Android Monitor is installed.
13. Questions to 4x4 Shop; Thanks to Ray for a response within the hour...
Q: The Android keeps going back to 24hour time, even after setting it to 12 hour in multiple locations.
A: You can go to setting-time-if you select original time will stay with 24 hours, if you select sync to GPS signal, you can do 12 hours format.
Q: The BACK button on the iDrive does not reboot the system per the instructions
A: The back button won’t reboot the system, mistake on the information.
Q: WIFI doesn’t automatically connect, even with settings set to do so;
A: You need to turn off the hotspot from your phone and turn it back on, time out on the hotspot from your phone.
Q: Do you have any insight why some E70 X5 installs don’t need the AUX OUT to OEM AUX IN connection to hear sound?
A: For E70, always need to run the aux cable from the power harness from android to your factory AUX jack.
Q: Is it possible to add the Developer menu option in SETTINGS>SYSTEM>ADVANCED>
DEVELOPER OPTIONS>FEATURE FLAGS>settings_seamless transfer? I would like to switch between audio sources: AUX OUT and USB Audio OUT. I successfully am using USB Audio Out to a DAC and coupled with a specific player app (UAPP).
A: You can activate the developer mode, but we don’t recommend customer to do any modification on that.
Q: Does 4x4 Shop offer a front camera setup compatible with my interior Rear View Mirror setup that has high-beam assistant and rain sensor? [I had to send pix of my cover (51-16-9-216-739)].
A: NO.
Q: How do I connect the TV Tuner?
A: You should have one harness with 4-5 RCA jack on it, that is the one for video and audio input, you can use it for your TV tuner. You can get the power for the tv tuner from your factory cigarette lighter adapter.
