I've tried a both a flash drive and hard drive attached to the USB port in my 2015 Acura RDX and both are limiting the number of folders shown to exactly 700. Both drives have a lot more folders than that. I've seen other threads mention this but haven't seen if it is a limit of the vehicle. If so, are there limits to the number of files it can read as well? Is there any workaround?

 

I have a 2015 RDX w/o tech package. This is the first time I've heard of it. But I never had that many songs on a USB drive though.
