ZHP:
I purchased an AVIN4 BMW headunit. I have installed a front camera (Avin product) works perfectly. Backup camera (Avin product) will not display image.
I purchased the wireless transmitter/receiver ... both illuminate but no image. I tried with just the cable/wire ... still no image.
Here is the setup
1. Factory setting "Prohibit Reverse" enabled
2. Wireless transmitter connected to reverse positive (blue yellow wire) and reverse negative (brown wire); plugged into backup camera and connected to the "Red" and "Yellow" RCAs that bridge between the backup camera and the wireless transmitter; since it is illuminated when vehicle is placed in reverse, I conclude all is appropriate
3. Wireless receiver "blue" wire connected to "pink" "Brake-IN" wire and "red" wire connected to "orange" "Reverse-In" (Note: me vehicle does not have a wire labeled "Camera +12V" as shown AVIN instructions; after conversing via chat with AVIN they state the I should use "Reverse-IN" for power; interestingly, they had me disconnect the "blue wire" to see if the image would display... it did not.
4. Using the wire/cable ... I plugged in the backup camera lead to cable that runs to the headunit; connected the backup camera "black" ground wire to ground and the "red" wire to reverse positive wire (blue/yellow); at the headunit, i plug in the RCA "yellow" cable to the "Rear Camera In" RCA; note AVIN told me to ignore the "red" wire which branches off the "yellow" RCA; I tried connecting the "red" wire to the "orange" "Reverse-In" ... no image displayed with or without the "red" wire connected
To further troubleshoot ... I though possibly the backup camera is not receiving a steady 12+, so I connected a wire from the battery directly tyo the backup camera ... same result ... no image
I am at a loss of what to do. The Avin customer service sent me two additional backup cameras ... same result no image.
Any suggestions ...
