First, go to the CarSettings app - click System Settings up the top, then click SYSTEM INFO.

Look at the "APPVER" line on the system info page. It will either say "K4811" or "K2501" depending on the software version. It's important to get this right, so you download the correct update file. Look at the APPVER line, and then download the matching update file from the links below.

1. Download ZIP and copy directly to a USB. Do not rename, or unzip the file. The file must be downloaded as a ZIP file, and not renamed. It should be called "update" or "update.zip" - if it has any numbers in the name , for example update(1).zip , then you will need to rename it to remove the (1).

2. Connect the USB to one of the USB ports on the unit. Ensure there is nothing else on the USB apart from the update ZIP file. Must be the only thing on the USB.

3. Go to CarSettings -> System Settings -> System Update and click begin update

4. Allow unit to fully update. Do not switch off or operate during the update

5. If that does not work at first, unplug the USB and put it into the other USB port on the head unit, then try the above again. You can also try reinstalling the file to the USB, and formatting the USB drive.

Then please go to carsettings - factory settings - 16176699 - customised settings - scroll to bottom , select the EXTERNAL MIC setting, then click SAVE.
