Is the APIM unit the same thing as the Image Processor? Bad cameras?

Sorry, thought I did. But it was pretty much saying it'll be the cameras since they replaced everything else already. Turns out it was an educated guess.

They are not the same things. The APIM is Accessory Protocol Interface Module. The IPMA is the Image Processing Module A and the IPMB is the Image Processing Module B.
The IPMA is located behind the windshield in the area where the interior rear view is mounted. It is used for Rain Sensing Wipers, Lane Keeping Assist, and Auto Hi Headlamp.
APIM
The APIM can be operated with the ignition in RUN, ACC, or OFF.
The APIM receives stereo and mono inputs. Stereo inputs include audio from the USB port, audio input jack, and connected Bluetooth media device. Mono inputs include audio from the outside device during a phone call and inputs from the SYNC® microphone.
The APIM sends stereo and mono audio signals to the ACM as fluctuating AC voltage. Stereo outputs include audio from the USB port, audio input jack, and connected Bluetooth media device. Mono outputs include audio from the TTS feature, incoming call ringtone, ringback tone, outside device during a phone call, voice or tone prompts initiated from the steering wheel switches and infotainment centerstack, route guidance voice or tone prompts, and SYNC® system instructions.
The TTS setting allows the customer to hear incoming caller information and incoming text messages through the audio system speakers so it does not have to be read from the centerstack infotainment display and/or device while driving.
The APIM consists of two internal modules: the CIP and the VIP. The modules are not replaceable individually, but can be programmed independently if required.
The CIP interfaces with all of the customer inputs to the APIM. It contains an analog-to-digital-to-analog converter, as well as the Bluetooth chipset. Any Application upgrades that are available to the customer are loaded directly to the CIP through the USB port.
The VIP provides an interface between the CIP and the vehicle inputs. Its main functions are controlling the APIM power management and translating inbound and outbound CAN signals.
The APIM requires programming when it is replaced.
IPMB (Vehicles Equipped With Rear Only Parking Aid Camera With PTBA or 360 Degree View Camera)
NOTE: The IPMB settings and configuration have no influence over the video signal from the parking aid cameras. The parking aid cameras provide a video signal any time they receive voltage and ground.
For vehicles equipped with a 360 degree view camera system, all camera views are produced by the IPMB, using input from one or more camera(s). The processed video signals are sent from the IPMB to the APIM on shielded, twisted pair circuits. The IPMB receives the video signals from the front, rear, LH and RH parking aid cameras through shielded, twisted pair circuits and determines which image(s) are sent to the APIM to be displayed on the FDIM. In addition to generating the camera views, the IPMB serves as a gateway between the front and rear
parking aid cameras and other modules on the HS-CAN2. It communicates with the front and rear cameras via the LIN and stores Diagnostic Trouble Codes (DTCs) for the cameras and the LIN in the event of a concern.
For vehicles equipped with a rear only parking aid camera system with PTBA, the IPMB serves as a gateway module between the video camera and other modules on the HS-CAN2. It communicates with the rear video camera via the LIN and stores Diagnostic Trouble Codes (DTCs) for the camera and the LIN in the event of a concern.

Just saw my old posting about a color hue/saturation issue I’m having with one of my cameras, and noticed Shadow2016 replied and was having issues then too. Dang man hope it gets squared away.
I still haven’t taken mine in yet…..figured I’d wait til more stuff creeps up and get it all done together.

I'll have to read the work order again, but they replaced the "left side camera" whatever that means and the problem went away. I now have a properly functioning backup camera. I'll post back again tomorrow after I read the work order a little. More. In depth

The 360 Camera view uses the front camera, the rear camera, and two side cameras mounted on the bottom side of the mirrors to create the overhead view you see on the display..
