I have been using an 8GB USB pen drive plugged into the car stereo USB socket to play music MP3 tracks on my in-car stereo system in my Honda Jazz Mk2 (2012 model).
Now I would like to use an external Hard Disc Drive (HDD), say 250GB, so that I have a much bigger collection of music at my disposal. But when I try doing this I get an error message on the car stereo ("unsupportable"), even though it is just MP3 files, as per the pen drive. Looking online, I wondered whether this is because the stereo's USB socket is unable to provide enough power to run the external HDD? Or is it because the HDD is too large (too many GB)? Or a problem with formatting (FAT32 and all that)?
Has anyone else had any success running an HDD drive (or an SSD drive) with the car stereo system on a Mk2 Jazz?
