It is possible to use a portable HDD as long as it is compatible with the same file system to which this model of car stereo corresponds.
The file system for the car stereo receiver corresponds to the Windows operating system (FAT16, FAT32) by mass storage class (MSC). It does not correspond with any other file system.NOTE:
- It is possible to connect a USB Flash-type drive formatted with the correct file system.
- It is possible to connect a portable USB rotational HDD that receives power from a secondary source (AC or DC ).
- It is not possible to connect a portable rotational HDD that is powered through the USB because the USB port on the car stereo cannot supply enough voltage to spin the HDD rotational platters.
