Note:
In this case, no rear camera is connected to the ESX device, but its function is activated in the ESX device. When reversing, the image of the rear camera is normally transferred, but since this is not available, the ESX device shows only a blue screen.

Remedy:
Disable the "CCD" option under APPS -> OPTIONS -> DISPLAY.

Remedy:
Disable the pause function under "Apps" >"Options" >"Display" >"Pause media whilst reverse".

Reason:
Due to the increased utilization of the navigation application, it is possible that the device does not respond to a quick touch. This problem may appear with OS Version 1.55 or 1.55-U1.Check the OS version under “Apps” > “Option” > “System”.

Remedy:
Proceed an OS Update to the latest Version. You will find it in the DOWNLOADS section.

Alternatively:
Enable under "Audio" > "Advanced" > "Key beep" and press and hold the desired Button for about one second. Thus you have the acoustic control if your command has been registered by the device.

Remedy:
Depending on the size and data on the stick, it may take longer to read it out under certain circumstances. During this reading time, a possibly existing LED on the stick is flashing up. Wait until the reading is completed. Delete unnecessary or not compatible files on the stick to speed up the reading.

Remedy:
To delete user files such as images or videos, please use the file manager (files) as described in the user manual.

Note:
These devices cannot be reset to the "factory setting".

Remedy:
You can connect a rear view camera on all ESX i10, i11, i20, i30 devices! Use the connection "Rear Cam Input" (refer to the installation manual or the label on the device) and the included 6-pin connector, which has the following connections:

Yellow RCA                        Video signal of the rear view camera

"REVERSE" blue cable      Reverse signal (12V)

"GND" black cable            Ground connection of the rear view camera

"+12V" red cable               Power connection of the rear view camera (Max. 500 mA)

Warning! 12V output power, as soon as 12V are connected to „REVERSE“!

Connect the camera via RCA to the yellow RCA connector. Then connect the reverse signal (12V as soon as the reverse gear is engaged, e.g. from the reversing lights) from the vehicle at „REVERSE“ (blue cable).

Exception:
If the REVERSE signal is provided by the CAN-Bus signal it is not necessary to connect the blue cable

Note:
The connection of the „GND“ and „+12V“ cables is not mandatory, but can used as power supply for the rear cam. If you don´t connect the “+12V” red cable, get sure to avoid any shortcut!

Finally activate the „CCD-Camera“ checkbox under APPS -> OPTIONS -> DISPLAY at the ESX device.

Note:

1. If the ESX unit is turned off, the display turns automatically on and shows the picture from the rearcam as soon you go into reverse as a apart from the safety function after engaging another gear, the display from the ESX unit turns off.
2. If the ESX unit is turned on, the display automatically switches to the picture from the rear cam, when the reverse gear is engaged and the device does not allow any other operation, all the buttons and controller except volume control are blocked for security reasons. Also, the device can not even turned off.

Exception:

At some VW cars the display can be switched by touching the screen between CCD rear cam and park sensors (PDC)

Remedy:
Check the proper connection (see point above) and the settings in the ESX device under “Apps” > “Option” > “Display”. Get sure, “CCD Camera” is activated.

Remedy:
You can change the picture settings when you push the right rotary controller. There you can switch trough the different settings:

Brightness > Contrast > Saturation

You can change the desired value with using the right rotary controller.

Note:

This also works with the Sources: “DVD”, “TV” and  “Camera”

The connection of a separate front camera is possible with the optional adapter VNA-CAM1 via RCA. Switch on the camera image via the button "Camera". Enable before the "Camera" switch in the menu (see manual section "Menu Assignment").

Note:
The original factory CD changer is unfortunately not supported.

Note:
This connection is unfortunately not supported. Use one of the connectors of the ESX device for USB or iPod/iPhone or similar.

Remedy:
Disconnect the battery for 15-30 minutes. The ESX device must already have been put into operation on CAN-Bus!

Remedy:
Disconnect the battery for 15-30 minutes. The ESX device must already have been put into operation on CAN-Bus! Recalibrate the park sensors by driving some meters.

Remedy:

The buttons "track forward / track back" does not work for audio control. But you can still operate all the functions in the MFA (Multi Function Display) menu as before with all four buttons on the right side of the steering wheel remote control.

It will be possibly fixed in the future with an upcoming update.

Note:

Check the installed yet MCU version under "Applications"> "Options"> "System". The Golf V platform requires a different MCU version (as of 04/2014: V2.14) as the Golf VI platform. All of our units are shipped with the latest Golf 6 platform MCU (Version 07/2013: V1.02EU). Let your dealer downgrade your device.

Remedy:
Check the installed yet MCU version under "Applications"> "Options"> "System". The Golf V platform requires a different MCU version (as of 04/2014: V2.14) as the Golf VI platform. All of our units are shipped with the latest Golf 6 platform MCU (Version 07/2013: V1.02EU). Let your dealer downgrade your device.

Reason:
A Bug in MCU version V2.04. The problem only occurs if “CCD_Camera” is deactivated in the “Display” menu and the reverse gear was engaged.

Solution:

Check the MCU version under “Apps” > “Option” > “System”. Let your dealer update your device to V2.14 (as of 04/2014).

Note:

This function is currently not supported for the Golf V platform. Possibly. It will be possibly fixed in the future with an upcoming update.

Remedy:

Probably it the previous original VW radio was not a navigation system and the arrow indicator function is not activated in the vehicle. Contact your VW dealer, he can unlock the arrow indicator function of the MFA.

Note:

Only the "MFA +" and the "MFA comfort" support the arrow indication (depending on vehicle and equipment)

Remedy:

This requires a software update of the ESX device. Please contact your dealer.

Remedy:

This AUX-IN is not supported, because it is not connected with the car CANBUS. The ESX CANBUS works with the car CANBUS, but in exceptional cases and different equipment variants, the functionality is not guaranteed. Use instead the VIDEO INPUT CABLE SET (refer to the installation manual Pg.4 # 5 - Slot J5) from the ESX device, which you can use as an AUX-IN.

The ESX device expects a CAN-Bus signal, which is not present in the radio preparation

Solution 1: Connect the CANBUS later on.

Solution 2: downgrade of the MCU version. Contact your dealer for this.

Attention: Make sure the latest version MCU must be installed again for the re-connection to the CAN-Bus.

Note:
The steering wheel remote control only works via a connected CAN bus.

Remedy:

Connect a CAN bus additionally.

Note: The original system works with fiber optic cables, this means it must be completely bypassed.

Solution 1: Route new speakercable from the ESX device to the original speakers resp. to the output cables from the original car´s amplifier

Solution 2: Install a separate amplifier to connect the oriignal speakers

Without the original Command APS System the original antenna amplifier will not be supported anymore.

Remedy 1: Locate the original antenna amplifier and activate it (usually by a 12V power cable).

Remedy 2: Install a new or separate antenna.

The setting of the time display is not possible after the Command APS was removed.

Remedy: Use the original Command APS system for adjusting the time or contact your Mercedes-Benz dealer.
