[MTCB Android Head Units Q&A] kaween:
Honestly ? And this is spoken as a ex-owner and still-owner of several other units (Ouku-retired, S150-died, AN21-U-will remain in use in 2nd car -and I'm still active in supporting and experimenting on that platform) :

By the way, I'm talking about exactly the same unit as JSP11 metioned prior to me.

1) standard sound is adequate at best when being used as-is. The stock EQ is laughable compared to most other units I've ever used, owned, tested or installed. But like with so many other units, install Viper4Android and the unit comes alive. I'd rather have seen a 9-channel, full hardware DSP&effects + programmable filters like on the S150 platform, but no such luck.

2)I have an active sub. Sound will be as good as your sub is, really. Note : there's NO control over sub-output. No cross-freq setting, no output power setting.

Honestly I don't even understand why they bothered to put the dedicated sub-output on this unit, it's useless unless your active sub can't cope high-level inputs of course.

3) the internal mic is crap. Even using an external mic is crap. The only way to get a usable mic quality for BT is opening the unit and do some (simple) modifications to it. After that it's still not brilliant, but it's usable.

4) Well, I love the screen of the 7" JY unit and it is definitly better than of most units I've played with. It's no IPS, not by a long stretch, but I've seen much more expensive units with screens that were totally useless. But depending on your dashboard layout, you might consider some kind of reflection filter for it, just like you would with any other LED-LCD-based screen.

5) yes. It has more strong points than it has weaknesses. It's fast (certainly the quad core version) As far I can tell, it's stable. It has WORKING RDS and RadioText (=good luck finding that on another unit and yes, it's a big deal to me), it has a very active community (always a good sign), it' is probably the only unit today that offers (non-official) tricks like cpu upgrades (people are upgrading their 2core cpu boards to a 4core cpu board on these things : that's pretty much unique). If you have a GOOD car antenna, the reception is good enough. It can be used with stuff like external DVB-T tuners (USB based, meant for Phones and such) and DAB+ usb sticks (.... software still needs a lot of work), and stuff that "isn't there out of the box" (Gala/SDVC for example) can be added but installing user-developed app's. Boot time is no issue to me : my units have an independant power supply to avoid reboots during crank ect ect (basically a small ups-like device with a dedicated battery in the trunk) hence it "boots instantly" when I press the power button.

Of all the units out there, this unit has the biggest chance of ever running Lollipop In my opinion, but that's just my opinion and no fact, and the different bigger brands that use this platform (KGL, KLD, ...) are very active and they still add functionality to their releases, where other brands either put a very stable and pretty much error-less version on the market but as a result, they add NOTHING anymore or fix none of the issues that still are found (like the AN21-U platform : nice, stable, good quality. Closed shut like Fort Knox. No significant development scene), units that (by chance/clumsyness of the the mfg'er - which dumped the complete code on the net) were broken wide open and have a good chance to become extremely cool units .... someday (Newsmy). And then you have the Ownice machines .... where the owners depend on the goodwill of one mfg'er who's taking his sweet time resolving issues I haven't seen since the first gen of anrdoid headunits.

There's no "one size fits all" : all these units have their pro's and cons. Depending on what you find important, one unit will fit your needs better than the other.

Again : this is my personal opinion, based upon the use and experience of several android-based car devices.

Take it for what it's worth.
