The Seicane I have is different from the Eonon. I have quite a few Eonon units in different vehicles and just the one Seicane that I just put in my X5. I have found the Seicane to be perfectly stable out of the box unlike the Eonons which required tinkering to work right. The best way to tell the units apart is the pictures of the back of the radios not the front. Just about all of them look identical on the front side.

The Seicane has an actual external antenna for the wifi which really helped with the wifi range for example.

As for gain controls look inside the "factory settings" option. All of my Eonons have individual gain controls for each audio type in there.

Yes, mine was a DSP non-nav car. The factory nav was garbage anyway! The difference between the Dynavin and the Android clone HUs is that the Dynavin N6 actually communicates with and still uses the DSP amp. The other units, best i can figure out, bypass the amp and plug into the speaker harness in the rear of the car. All of the Dynavin N6 connections are in the dash unless you happen to have a car with the factory nav. which means that the radio module is not actually in the dash and is in the back. It still uses the factory DSP amp and actually controls volume by adjusting the output of the amp. Just like the factory unit does.

Here is a link to the official install thread for the Dynavin N6 that is a sponsored thread by JT Distributing. You can scan through the VERY long thread and see that Jeff takes customer service very seriously. You won't be disappointed, and it sounds like this unit and how it functions is tailor made for your wife.

Good luck with whatever unit you land on!

I think I read that thread in my pursuit after purchasing this unit.
Mine is factory Nav wich made testing it out allot easier as I just simply plugged stuff in the back.
I think the problem with the eonon stuff is that the DSP is set to a default audio value and then just amplify the signal being sent to it.
This is why you get distortion.
You either have a variable output to a static amplifier or a static (fixed) output to a variable amplifier that is NOT amplified, however some factory car amps were designed to use a variable high level input, that way they could throw the same stereo in a premium car vs a base model.
You never run a variable amp to a variable amp you'll get this situation.
Running a high level input into a low level input will give you lots of distortion, a lot of people think the can just run the speaker outputs to their factory amp and find out its sounds awful and is super loud at low volume.
Basically an amp is going to output a certain amount of distortion, feeding the to another amp is only going to amplify that distortion along with its own which quadruples the amount of distortion at output.
That's why you use preouts to amps, it's preamplification has a certain amount of distortion from the get so it gets overall exzagerated by amplifying multiple times, hope that makes sense.
The factory unit uses a single wire per channel to the DSP that if I remember right is slightly variable, I think less then a volt +\- but it's been along time since I've tested that, was along time ago.
All the X5 I've done (with DSP) have been a complete gut from head unit to amps and sub or using the factory DSP to a summing device like A bit Ten or bit one to keep the factory components but add aftermarket speakers and amps.
Has been a long time since I cared to check what was being fed to the factory amp as it either gets removed or a deal with it after output.

Getting ready to go on vacation soon, so all dig more into the dynavin and see if I can't pull some actual specks.
Thanks for all your input!
