All of these are basically the same units with a different name/brand. Besides the Avin which is a Premium offering, you can feel good about looking for the >1.5Ghz 8 core/32GB ROM spec. Once you've found the style/look you like, the brand is pretty meaningless. Even the Avin's function does not appear very different from the others, but the premium product does come with the Resler USB already integrated.

Like buying a piece of hardware used to be, look for:

• Processor type, cores, clock speed
• >= 2GB RAM
• >=32GB ROM
• Appropriate resolution for screen size.
• Harness included or not (added cost for Nav vehicles)
