CDR31 Radio Modification

1. Remove the

radio from the

dashboard and

bring to a bench

top for

modification.

Use something

soft to protect

from scratches.

2. Remove (2x)

screws from the

top of the radio

face.

3. Using a small flathead screwdriver, carefully pry all clips (while applying pressure to

remove screen) around the plastic radio face. The entire front LCD panel and button panel is

connected vis ZIF connectors only (no ribbons to the radio chassis).

4. Lay the front panel

assembly down (face

down) on a soft mat.

Disconnect (2x)

ribbons shown.

5. Orient the provided modification ribbon like shown below. Connect the wider

ribbon into the wider connector as show. Make sure the pin-side faces down on

this step.

6. Carefully and slowly (do not tear ribbon), flip the ribbon over such that the smaller

touch-ribbon side lines up with the OE 4-pin touch connector. Once again, the pin-side

of the 4-pin ribbon must face downwards.

7. Once the ZZ2 ribbon is

connected to the board,

connect the leftover OE

ribbons back to the ZZ2

ribbon. When this step is

completed, it should look

like picture here (right)

8. Using pliers (or

similar method), cut

off 1 metal tab from

the radio chassis

mount as shown.

9. Using cloth tape (or similar method), lay over the serrated edge from tab removal

(step 8) to protect the ribbon. Be very cautious when lining up the screen face to the

ZIF connectors (there are alignment pegs towards the middle to help). Also pay close

attention to the exiting ribbon when connecting so as to not pinch/sever anything.

10. Route the ribbon

like shown leaving slack

along the way. Tape

down as you feel

necessary to route to

the back side of the

radio.

11. Connect the provided

Touch/Video PCB Module

to the back side of the

radio like shown using

the double-sided tape. It

is best to leave a 1/4" of

space between the left

and bottom edge for ease

of installation back into

the sub-dash.

Main Menu

Car Setting:

Allows adjustments for

camera(s) and MIC options.

These options are specific to

the how the interface

handles camera triggers and

types (data vs analog wire,

OEM vs aftermarket etc). A

few other vehicle-specific

settings can be found here as

well.

General:

Allows adjustments for global

volume control and

navigation (specific) volume

control output. Also there is

an option for auto-pairing the

user’s handset.

Selecting ‘Settings’ will bring you to the ZZPLAY Interface Setup

Menu with all options pertaining to the specific vehicle and install.

The next few pages overview the ZZPLAY interface, navigating settings and explains

entering/exiting all menus. There are (2) menu systems that exist outside of the OE radio

system: Carplay (or Android Auto) menu and the ZZPLAY Interface Menu. They operate

independent of each other (the ZZPLAY Interface menu will function regardless of whether or

not a phone is connected to the module). Settings found inside Carplay will only affect

CarPlay functionality. Settings for the ZZPLAY Interface control things like reverse camera

settings, audio output control settings and other vehicle/interface-specific parameters.

ZZPLAY Interface Settings Menu

Question: I can't hear any audio from the CarPlay/Android Auto system.

Answer: Your OE system must be resting on AUX mode in order to hear any sound from the kit. This includes during phone calls. NOTE: Some systems AUX

input are not labeled 'AUX', it may be labeled 'Media Interface' or there may be an audio conversion to the vehicle's USB input. Check with your installer for more

information.

Question: I'm hearing reports of a lot of echo or delayed echo on audio during a phone call. Why is this happening and how can I eliminate this?

Answer: This happens because we are using the OEM AUX input for audio, and the AUX path travels through the OEM amplifier, where there is active time-

alignment & processing on this audio channel. There are a few ways to fix this problem, and there are Pros & Cons to each choice:

1. Use the OE Bluetooth system to handle all phone calls, and answer all incoming phone calls from the steering wheel, always. To dial out using

this method, you must use SIRI or voice command activation (typically hold control knob down for 4 seconds). Some vehicles, when

using the CarPlay/AA control in recent calls, the system will still use the OE Bluetooth to handle phone calls, but not all vehicles will

operate this way. NOTE: This method will sound the best for both parties on the phone call - to use this method, you MUST be paired to the OEM

Bluetooth system simultaneously with the ZZPLAY unit. PROs: sounds the best, and regardless of what audio source you're currently on, using this

method will switch to a 'phone call state' and return you back to the source you were on (FM, AUX, etc) once the call is ended. CONs: Your phone

must connect to both the ZZPLAY unit and the OE Bluetooth for every drive, and the reliability of these connections happening properly upon every

startup will be lower (only about 90% vs 100%).

2. Use the built-in 'AEC Auto Setup', or 'Call Quality Test', or 'Echo Cancellation' tests to adjust MIC settings for the microphone input of the ZZPLAY

unit. These tests are found in the ZZPLAY setup menu typically under 'Audio' or somewhere similar. Some vehicles require a level of adjustment

which will never be achieved, in these cases use the OE Bluetooth system (see choice 1). PROs: If this method works, it is the most reliable way of

using the kit. CONs: You MUST be on AUX in order to hear the person you're speaking with. IE: if you use FM or SAT, while using the visual from

CarPlay (maps, for example) and a phone call comes in, you must switch to AUX mode before you will hear the person when you answer the call.

This is very cumbersome which is why we suggest to stay connected to the OE Bluetooth and allow the car to handle the phone calls.

Question: Sometimes my phone won't connect lately / Sometimes when it connects the screen goes black / Sometimes CarPlay kicks me out back to the interface menu.

Answer: For iPhone users, you must perform a 'Hard Reset' on the phone in use on average twice a month to clear certain cache and reset the processors (this

will not wipe any data). Google search 'Hard Reset iPhone 13' (or whatever version iPhone version you have) and perform that task. After this is done, you will see a

difference in speed and reliability (of pairing/connecting).

Question: Incoming text responses from SIRI are silent on CarPlay. It mutes the audio but I don't hear the read-out.

Answer: This often happens for 2 reasons: The iPhone needs a hard-reset (see previous question), or the phone is connected to the vehicle's OE Bluetooth for

both phone calls & audio (and the text read-outs are being sent to the vehicle BT source - you're on AUX source). You want to be connected to the vehicle for

phone calls ONLY - for iPhone the only way to make this distinction is to adjust the phone setup on the OE radio side. Find your phone (name) in the Bluetooth or Phone

setup in the OEM radio settings and disconnect as an audio player. NOTE: not all vehicles have this option, but it seems to happen mostly with cars that do have this

option (Lexus, etc).

Question: Using Android, I cannot get the phone to reliably connect wirelessly (or at all).

Answer: Android phones are more finicky and iPhones with their wireless connectivity. Make sure the OS is fully up-to-date. Clear the cache on the Android Auto

application. The Android OS must be at least version 11. Some phones (TCL, Motorola) seem to have protocols that don't play nice with every system. If you run into this,

use a good USB-C cable for the Android Auto Connection instead.
