[Android Head-Units] TripFlex:
So i've had my KLD RK3066 800x480 for my 2011 Mitsubishi Outlander for over a year now, and I think it's time to upgrade, and was hoping to get other opinions on it.

I originally was looking at just upgrading the SoM to RK3166, but I also want the higher resolution screen, so I think with the amount of work it would require, I might as well just sell my current one and purchase something new so not have to deal with the hassle.

Here's one I was looking at:

These are the main issues I have right now with the KLD RK3066 800x480 (my current one):

Constant lag during normal usage, inability to run multiple apps at same time (Waze and SoundCloud)

GPS constantly takes 10-15 to get lock everytime

So called "3G Support" is non-existent

WiFi was pretty bad (got a little better with HW mod to external antenna(

Constant Lag

From what i've heard others say, and read on the forums here, it seems like going to the quad core from dual core will resolve some of the lag and running multiple apps issues I was having, but I've also seen the RK3188 being talked about/used for a while now, and I would hate to purchase a new unit and then a month later something new come out (the tech struggle we all deal with heh) ... So is the RK3188 the best available out there right now? I know my situation is different because it's not a standard double din, but maybe there's another option I haven't seen or missed? Maybe the RK3288 or some other octa core?

GPS Issues

Since i've had the unit the GPS has always been flakey, tried using every GPS app possible, even purchased a new GPS antenna without any luck. I did post a thread and someone mentioned that my GPS may be losing it's almanac, so that may be the issue, but at this time i'm not sure. Either way I just want some type of reliable GPS because it sucks sitting in your car waiting forever for GPS.

"3G Modem Support"

I'm currently using Google's Project Fi for cell service, and you can have multiple SIM cards under your account, so I ordered one, as well as a "supposedly supported" 3G dongle, the Huawei E182E, which has never worked properly. The only time i've been able to get it to work at all is by using the PPP Widget app from the Android Play Store, which even then, would only work for maybe 10 minutes and then crap out on me again. From everything i've read it could be due to the amount of power required by the USB, but either way, I just want something that will work correctly without having to mod the unit just to get it to work with something it's already "supposed" to work with (that and LTE would be a lot cooler to have than just 3G).

I was also thinking of just getting something like this:

To be able to get LTE speeds and not have to worry about dealing with trying to get it on the car Android unit, but not sure if LTE is even possible on these car android units or not? Thoughts?

With all that said, does anybody have any suggestions, comments, or bashing they would like to throw my way :p

I don't mind paying a little more for something that is higher quality, better processor, memory, etc ... but it seems that everything I can find online is all pretty much the same package deal, just sold by different vendors.

Thanks ahead of time for the input guys!
