You may wish to upgrade your APIM firmware to get features like radio logos and calm screen.
Before starting this process, it is recommended that you try making the AsBuilt changes to try enabling calm screen and radio logos first - Approx 2018 and onward vehicles are likely to have this update anyway. (NOTE: Once you have made the AsBuilt changes, perform a master reset of your APIM and check that radio logos and calm screen stay enabled. If they disappear, you will need to follow this guide to make the changes stay permanently)
Health Warning: This is NOT the same as updating to Sync 3.4. It involves specialist hardware, risking having your Sync module (APIM) ‘bricked’. Many users successfully carry out this procedure, but it is extremely important that you follow the instructions carefully.
Do not think you can use an alternative adapter instead of the OBDLink EX, you will brick your APIM. Configuring AsBuilt and flashing firmware are two different things.
Make a backup of your AsBuilt before commencing the update.
PUT THE CAR ON A CHARGER – THIS IS NOT OPTIONAL!
Make sure your laptop is charged up fully, and is reliable. Make sure it wont sleep/turn off during this.
Use a decent adaptor – recommend a good branded one like OBDLink EX (cheap ones probably will kill your APIM permanently). Do note that just because your adaptor works for ‘normal’ AsBuilt configuration, firmware updates are much more intense so good quality hardware is mandatory.
Try to use a USB2 port rather than USB3 - OBDLink EX has reported compatibility issues with USB3 ports.
Forscan experimental version 2.4.1 is needed, available here:
Forscan beta 2.4.1 requires a paid for extended license to download additional firmware files, and enforces the use of specific adapters (including OBDLink EX)
APIMs starting with the letter ‘G’ at the beginning of their part name (e.g. GJ7T-14G370-CM) are known to be more difficult to flash and users report an increase frequency of them being bricked. Letters H, J, K and upwards are much more resilient.
Upgrade your OBDLink EX device firmware to the latest available here (see guide below).
It is important to understand this is not 100% safe, if the process fails the chances are your APIM will be ‘bricked’ and require replacing.
Upgrading The Firmware
- Turn your car onto accessory mode (ensure your APIM is on and has fully started).
- Open Forscan and allow initial scan to complete.
- Select the chip button on the left, then APIM firmware update.
- Take note of your current versions, if you need to revert for any reason you can get the files manually from https://www.ucdsys.ru/calibration.
- Click on the Download button below – this will download the necessary files ONLY but NOT install them at this time (Internet connection is required).
- Once download is complete, make sure to use Test run SBL .
This will cause the APIM to reboot, and will start again as normal. Make sure the log states the process was successful.
Next, click on the Program! button. If your battery is too low, it will NOT allow you to proceed.
- Once the process has completed we can now enable Radio Logos and Calm Screen, Click the Stop button at the bottom and select APIM (AsBuilt Configuration).
8a. IF YOU HAVE DAB (UK/EU): Set 7D0-02-03 to X 6 XX-XX (keep the X’s at your current value) and press Write.
8b. IF YOU DO NOT HAVE DAB (USA/Rest of world): Set 7D0-02-03 to X C XX-XX (keep the X’s at your current value) and press Write.
- Once done, restart your APIM and you should have options for Station Logo in Radio Settings and Calm Screen in Display Settings . If you do not immediately see these options, carry out a master reset.
UPDATE: Issues with Sirius: There are known issues with Sirius radio logos not displaying, despite this update. It can take a number of days for them to appear if at all - unfortunately there is no known ‘fix’ if they do not appear at this time.
Upgrading your OBDLink EX Firmware to Latest
Before using your OBDLINK EX for the first time, you must update its firmware to the latest version. Ensure you update using a computer with a reliable power supply (ie, not a laptop on battery).
Go to: https://www.scantool.net/downloads/updates/obdlink_ex/ and download the latest available version.
Once downloaded, you must unzip the downloaded file to its own folder (Right click > Extract Files)
Double click on ‘StnFirmwareUpdater.exe’
- Ensure no other devices are connected to your machine, and select the correct COM port (this depends on what is connected, if you only have one option, it is probably correct. If there are multiple, you’ll have to work out which one is the correct one from your Device Manager)
IMPORTANT: Set the baud rate to ‘AUTO’:
- Click Upload Firmware, and allow it to update. Once complete, you can Exit and start using the adapter in Forscan.
