I really did try and search for this, sorry if it's already been asked, but I know the difference between the 700, 900, and 90, but what changes between those and the f500?

Thanks

It's not an in-dash unit, it's a portable unit.

There is no amplifier/speaker outputs, although there is a separate amplifier available to hook up to it so it acts like any other car stereo, supplying audio to your car's speakers.

There is no disk drive. Only SD cards and USB drives can be read.
