Well we all know how much a pain in the behind it is to replace our stock 1.5 din stereo with one that is of decent quality, if there is one. Going with a 2 din is too much of a hassle to cut and make space. Which to only see all of that hard work and frustration came to out as a crappy results.

That being said, I'm just going to consider a 1 din. Some of which come with an auxiliary port and a USB input for a thumb drive or external hard drive.
Would anyone happen to know what the limit for for space recognition is for a hard drive?
If a HU comes with only 1 USB port, is it possible to add an adapter to have 3 USB inputs?

Thanks in advance.
