How you make the camera work for front view on alpine INEw927hd? How do you connect the camera that came with the unit?

If your Alpine INE-S920HD head unit keeps shutting off after a few minutes of starting the truck and your backup camera appears dark, it could indicate a power or wiring issue. Here are a few steps you can take to troubleshoot the problem:
Check the power connections: Ensure that the head unit's power and ground connections are secure and properly connected. Make sure there are no loose or damaged wires. Check the fuse for the head unit to ensure it is not blown.
Verify the power source: Confirm that the power source you are using for the head unit is stable and providing sufficient voltage. Consider checking the vehicle's battery and alternator to ensure they are in good working condition.
Inspect the wiring for the backup camera: Check the wiring connections for the backup camera, including the power and video cables. Ensure that they are securely connected and not damaged. A loose or faulty connection could cause the camera to appear dark.
Adjust camera settings: The dark image from the backup camera could also be due to incorrect camera settings. Check the settings menu on the head unit to adjust the brightness, contrast, or other image-related settings for the backup camera.
Reset the head unit: Perform a factory reset on the Alpine INE-S920HD head unit. Refer to the user manual or contact Alpine customer support for specific instructions on how to reset the head unit.

Remote controls don't have manuals. They have marked button and your press the buttons. The Audio unit it connects to does have manuals. The RUE-4190 does have a manual.

No wiring diagram exists. Take it to an electronics technician and they can test the components. Put new batteries in it and try this test. Using the front facing camera of your smartphone, face the infra red sensor of the remote at the camera lens and press an button on the remote. If the remote is working, you will see a red light flash. It only works on the front facing camera.

Contact Crutchfield, as they supply nearly all of these.

Did you try fresh batteries in the remote, they may be 10 years old. It may also be that the new remote is faulty. Use the front facing selfie camera in your smartphone to see if the IR transmitter lights up?

Unit: Alpine INEW927HD
ISSUE: GPS not working - spinning to connect
Symptom: GPS goes into an Off State
Screen states - Auto Detecting GPS Receiver - This went on for days.

My Fix to the issue: Hold down the reset button on the front of the unit for 15 seconds.
After the unit restarted GPS and Maps worked just fine.

If the alpine 8020 is a deck(head unit) the wire diagram is as followed:

Red: Accessory
Yellow: Constant Power
Black: Ground
Orange to orange/white is a illumination or dimmer wire.
White: front left speakers
Grey: front left (white black and so on usually the negative on the speaker connections)
Purple rear left (purple black = neg)
Green: Rear Right
And if a video deck(light green is park brake)
(which is usually just a ground) so legally it needs to be on your park brake but can be grounded to make it work.

Speakers? (Terminals larger one is positive, smaller one is negative) Place capacitors on if needed to filter out and clear up bass

Hope this helps couldn't look uo what a alpine 8020 was..

Typically the orange wire in a car stereo are connected to the + always on ( it's usually for back up memoru). ordinary AWG # 18 flat cord will be sufficient for the purpose

grounding the brake wire will allow you to view video while driving but may require an sequence (on off on or whatever it calls for) to turn on video playback so i suggest grounding the wire and putting a small toggle switch on the wire. i have done this in many cars during my strent as a professional car audio installer

This may help. Alpine typically controls their internal amps one of two ways:
1) menu setting for external amp or defeat internal amp
or
2) top of the unit (with it removed) there maybe a series of switches by channel (front, back and sub) on the unit. My current alpine has the switches on top.

1)When you connected the amp to the head unit, did you run two pairs of RCA cables for front and rear reference or did you only run one set of RCA cables from the rear out to the amp?  2)If that's not the case and you did ran two sets, on your amp, swop the rear and front RCA cables. If the rears go quiet and the fronts are loud you now know the issue is either in the cables or how the head unit is set up. If the fronts are still quiet, check your Amp's gain, frequency and filter setter settings (if available). If those settings don't change anything you may have a faulty amp. 3)Check speaker connections, seems trivial, but you never know.
Message me back if nothing works and/or you get stuck.
