This update addresses the following items:


SWC Interface Revision


The built-in learning steering wheel control (SWC) interface of the ADVUNI300 has been revised. In order to support more vehicles, the “learning ability” has been removed and now supports a “pre-defined” (Preset, non-programmable) protocol that is compatible with PAC brand SWC adapters. Other brand adapters that use a similar programming protocol my function but have not been tested.


Preparing the MicroSD card


Note: You need a 4 Gigabyte Micro SD card; this can be purchased at any office supply store. Insert the Micro SD into the adapter and plug it into your computer. This can be a SD Card slot or USB slot depending on your adapter and computer.

MicroSD card should be formatted to FAT32 before update procedure.


** Unzip the software update zip file ->ADVUNI300-04_17_2015.zip”.


Place the update files into the ROOT directory of the blank MicroSD card.

There should be no folders on the MicroSD card except the folder contained within the update files. See below image for reference. All files are in the Root Directory of the “E” drive. (External drive letter may vary from PC to PC).

**NOTE: Firmware files are compressed. When you download the ADVUNI300-04.17.2015 file to your computer you will need a program to uncompress the files. This is called “UNZIPPING”. There are many free programs to do this and your computer may have already have a program built in to do this. If not we recommend WINZIP. WINZIP is free and can be downloaded here: http://www.winzip.com/downwz.htm Follow the instructions at the WinZip site for use of this utility.
