[MTCB Android Head Units General] tmiller101:
My friend these android units will not meet your needs.

1. Good quality bluetooth for music and phone calls -

No. Problems abound with the bluetooth in theses units, see multiple huifei mic mod threads.

2.Keep SWC (Steering wheel control)

Yes and no. Some people have no problems others have nothing but problems. There are solutions but it might take you some serious TS time before you find a solution.

3.Good Navigation GPS

Yes. Since it is Android based install any app you wish.

4.Ability to just plug in a suitable harness (no cutting wires etc.)

Not sure why this would be on the wishlist. I'm sure joying has an ISO wire harness, but you should contact them. They can better answer that.

5.Ability to play audio from RSE (rear seat entertainment) . A nice to have is to keep the ability to control RSE from SWC

If you are good with electronics I would say you could probably rig something. These units are built with video outs and have options for headrest video screens. Again this is not plug and play but you should be able to tap in.

6.Another nice to have is reversing camera.

Yes. That an easy task.

Q1: Has anyone installed a CarJoying (RK3188) on Hyundai Santa Fe 2007-1012 model?

No. VW and it was not a walk in the park.

Q2: Does my car indeed have a Amplifier, if so, do I need an HU that has preout or would it work equally well with Line Output Converter like the Scosche SLC4?

This is tricky. My car has a factory amp controlled by the CANbus. Major thorn in my side. Since I was unaware, Joying sent me a Bus decoded that was not compatible with my car. At the time they didn't support factory Amps that are controlled by a CANbus. So I went to PAC and bought one of their decoders. Except they didn't tell me that their decoder is not compatible with Joying head units. SO I lost SWC features and the MDF features. A guy on youtube used a PAC decoder and set it to Pioneer and it worked fine for him. But if did not for me.

Q3: will I be able to control RSE from the front?

Can't help.

Q4: What adapters would I need? I looked it up on Crutchfield and it listed the following four. Anything else missing?

(a) PAC SWI-RC Steering Wheel Control Adapter

(b) Scosche HY1612B Dash Kit

(c) Scosche SLC4 Line Output Converter

(d) Metra 70-7302 Receiver Wiring Harness

From my experience, you will have to walk the dog to get the true answers. A lot of this is experimental, works in one vehicle not in another. Something that works for me not for you. And the again Joying have have everything you need. Email them and start asking them these questions. They have a very responsive and knowledgeable staff. They have answered all of my questions very accurately. I screwed up the factory amp thing.

Q5: Any recommended installers in the Dallas/Fort worth area? Where would I look for local installers?

Again can't help.

Bottom line is consider these units like beta versions of software. They are fun to play with and have many useful features. But by no means are they plug and play. I was in the same boat as you, I wanted to upgrade my wife's system. So I bought one for myself to make sure it was something that would meet her needs and discovered it doesn't. However, its been an enjoyable adventure for me, but not for her.

Hope this helps. Just trying to set your expectations more realistically.
