If I was coming from a base-model stereo *and* this thing actually worked, I can't say I'd be terribly disappointed. It's fairly well put-together for what you pay for it ($410) and if it sounds decent I'd be content feature-wise.
Life expectancy? 2 years? 6 months? 90 min? 0?
I think the general business model (on their end) is that the units are compatible in replacing 90% of the base models stereo for whatever OEM they're targeting.
Is there any sign of any of the major audio manufacturers (Alpine, Pioneer, Kenwood) intending to offer a direct replacement for the MFT?
