My GUIII 4.8

Eonon Head Unit GA2114:

This is going to be a bit of a lengthy post to explain this as it can do pretty much anything, much like todays phones.

The Head unit runs an android based system. You can customize it to suit your needs/ wants which is why I chose it in the first place
First of all I will explain the android based head units as a group. There are pretty much 2 main types. MTCB based and MTCD based.
Most of the head units come from the one factory HuiFei then rebranded from the reseller. Pumpkin, Eonon, Xtrons, Erisin just to name a few.
While the externals look a bit different the internals are the same. I found this out while finding the firmware versions.
Which one have you got? Go into Settings and scroll down to about Device. You will see MTCB or MTCD in the MCU version. The build number will give you what chipset is used in your device.
NOTE: the firmware doesnt care what the "factory" sold it to you as. Its a HuiFei unit and the only things that matter are what chipset it has, the screen resolution and if its MTCB or MTCD. EVERYTHING ELSE is irrelevant!!

There are 2 basic types of processing chipset options available. RK3066 dual core and RK3166 Quad core. 2 screen resolutions are also available 800x 480 and 1024x600. Both of these specs are important to know as it determines the ROM type if you want to upgrade the software.

For the purpose of this , the Specs on my unit are RK3166 Quad core with 800x480 screen resolution.

Out of the box this unit is very capable. For $340 I got the head unit, reverse camera and Aussie Sygic maps as part of the deal. Included standard was the GPS receiver, external microphone for hands free , ipod connection plug (30 pin old Apple connector, not the new Lighting type) , USB cables to plug in your phone or flash/hard drive or even a 3G dongle, WIFI and all your usual plugs and connectors.

This is the way I run it for the first week to make sure it was all working fine. Bluetooth worked pairing my phone for calls and music no problem, WIFI connects at home for updates to software etc or to transfer files I want it to. Radio works great and so does playing movies.
I can output the signal to 2 other monitors if I wanted and also have an extra video input for an external DVD player or other camera if I want (think front mount dash cam with the ability to record to the unit)

This unit doesnt have a cd/dvd drive at all. I wont use it. The model with the DVD drive was a 6.2" screen and mine is 7" due to having a little more real estate available. I will have all movies etc on a flash drive when I want them.

I have changed the boot screen to show the Nissan logo on boot up, just for a little bit more of the factory feel.

Now onto what I want it to do......

I want it to read temps and pressures etc from the sensors via the ECU instead of cluttering up my dash with a million different guages.
This is where I run into a problem. The bluetooth OBDII/ELM 327 adapter I have would not connect. Why? Because it had a different name that didnt include OBD in its name and the head unit with stock firmware would not recognise this. My adapters name was PP2145. Bluetooth names can not be changed.
Yes I know you can change the name on your phone to whatever you want, but thats what your phone calls it, NOT what its true name is.

Solution, Flash the head unit with new firmware and install a program that lets me get rid of this limitation. Simple.
Now my OBD reader connects and I can get info from Nissan Data Scan II like water temp , throttle position, RPM and a few others. Im trying to find some other PID's I can get readings on like oil pressure and transmission temp. I have read fault codes with this too and sucessfully cleared them.
Im also trying to get Torque Pro to read data on this. I havent spent enough time with it to get this to happen yet. I do know the Nissan EX plug in does not with with the TB48 so far either.
There are a few other ones I am yet to try like Car Gauge PRO which apparently will read Consult II properly. I will report back on that.

If anyone wants I will post up a bit of a guide and software/ firmware recommendations for these units. Its very simple to do, even for the technically challenged.

Now I have custom firmware on the head unit , I can do pretty much anything from set auto dimming times based on GPS location/time to make everything I want run automatically on start instead of waiting for it to initialize.
What else does it do? Gets rid of the POXY 1 GB size limitation for installing apps and data related to them. You can now utilize the whole 16gb
this also lets you install different launchers,home screens and button layout customisation. Oh and the stupid non working weather app is now gone and replaced with a working one. If you dont like the one bundled with it, simply delete it and use something else. Dont like the keyboard? Change it. Want to just lower the music when selecting reverse instead of it totally cutting out? Simple, tick a box and its done.
All the apps I use on my phone can be installed on the unit.

Anyway even though this post is long and I could fill pages and pages I will leave it there. If anyone wants to ask questions go ahead.

Cheers
Mike
