Yes, sufficient.

But with the price you got from Soundstream, you can get better spec and deal else where.

From my view, Soundstream pricey.

Actually, if you do not mind, you may forget about brands. Those come with brands are basically over-priced.

I believe most ppl will agreed, 90% android head units in the market (brand or non-brand) are sourced from China mainland, meaning inside the head unit, more or less same.

Just shop at the shoppe and choose 4gb-8gb non-brand, with the similar price tag as the branded one, you can get 6gb-8gb.

Note: I dont think brand like Mohawk. Soundstream, Dynavin will develop / invent the player themselves without the economy of scale.
