Dynavin D99 vs. AVIN Avant-2

Okay, so I'm in the market for an aftermarket head unit to replace my stock nav. I've narrowed it down to one of these two.



First off there's the Dynavin D99 (I would purchase the one with Android)...

Then there's the AVIN Avant-2...

So, from the research I've done both of these units look factory and are a direct fit. They both run Android and look to be top notch from what I can tell. I'm trying to determine which one I should get, let alone what the major differences are. From what I can tell Dynavin and AVIN seem to be closely related, that or I'm missing something.



Now if you look at the Avant-2 it compares it versus the D99 (though I think it's comparing it to the Windows model) and it clearly ranks the Avant-2 as being much better. Of course it has to be taken into consideration that this is coming from the AVIN site so there could be some bias going on.



My question is this: Has anyone run either of these head units? Is one of them better then the other? I'm just looking for some unbiased opinions. I would like a unit that runs Android, has WiFi capability, can use my phone as a hotspot, works with Bluetooth, and basically functions just like a smart phone but in my dash.



Any input is appreciated, thanks guys!
