Since it was all plug n play there was no reason to disconnect the battery.

Just a heads up, If you have a 2011+ GL, you do not have to run a Farka cable to the Sirius fm box. The FM farka is attached to the wire harness, just find it and remove the foam around the cable. Check out my new thread for more details and pictures.

Sorry, but that's not True Post #74 which shows my Factory Farka.. when i connect an antenna to it i get nothing! so it may work for some but not all..

Thats interesting. I wonder if its the Avin antenna connection or the wire harness? I have 2012 GL550 with HK and rear entertainment system, your picture shows the antenna is wired just like mine. I didn't have to make any additional connections to get 12v to the antenna, other than color coded wiring. Granted, I used a different most/interface and a different radio. But you would think the process would be the same.

my unit works pretty good so far.. but i have a question.. so when i plug my iPhone into the unit via auto Box and the Car-Play appears.
if you the music playing eg: AM/FM or SD Music playing while running Google Maps thru your Car-play Does the Music Lowers so you can hear the Directions?
mines doesn't lowers :-( so however lower the music playing that how loud the direction would be.. any fix for that?

2007 GL450 back up camera issues
 

I don’t know which cables I have to connect for the back up camera to work. I’ve read through this thread and I read that I would have to splice the rca cable but which one and where do I connect it to?

In my experience there is nothing to splice if you have the pig tail. You just have to find the correct wire to connect with the pig tail.

You need to purchase the optional pig tailhttps://avinusa.com/9-touchscreen-multimedia-navigation-system-for-mercedes-benz-ml-gl-2005-2012-model-px6904gb64-mlgl.html

So after installing my Joying radio and antenna directly to the head unit, I thought the radio had great signal. Turns out, it only got good reception in my garage and I never bothered to check the signal after. Seems like the only way to get the antenna to work properly is to run the wire from the rear sat radio to the head unit as suggested above. Just fyi.

i see that Avinusa Came out with Android 9.0 Pie wonder if we can update the Software on our Unit that has Oreo 8.0

Do you have full control of steering wheel buttons? My phone and voice command buttons don't work on my Joying (could be the interface or connections though). It does allow for hot buttons so I can use my track buttons for picking and up and hanging up calls. Does the track info show in the dash screen?

I'm still not able to hear the other person on the phone through Bluetooth since I first installed my unit. I still have to click on my phones speaker to have a conversation. :wall:

did you connect the microphone that it came with? Does the music info show on your dash screen?

yes my Steering Wheel Buttons Work To Change the Radio Station/MP3-Tracks and also the Phone Pickup/Hangup Work
the Voice Command Doesn't Not Work,

Im wondering if its the interface I got or how I connected it, my phone and voice command buttons don't work. Everything else works fine. The Avin unit says it displays track titles on dash, but I've yet to hear anybody say that it displays. I like my joying, but it if I can get all steering controls and dash display, I would consider switching to the new Avin.

no track titles in the Cluster but you do see the Radio Station, And the MP3 Track Number!
Volume +/- works
Phone Hanup/Pickup Works
Track/Station Search Works
Voice Command Don't Work

Does the factory backup camera work with the converter cable you can buy from Avin?

No microphone came with it, I connected it to the OEM microphone with the adapter that came with it. No music info shows on my dash screen, only the radio stations when I pull that screen up which allows me to change stations via the steering wheel controls

Yes, the adapter connects to the factory camera and it works. The AVIN adaper is RCA on one end and Fakra on the other. Depending on the year of your vehicle, the adapter connects to the existing Fakra connector or you need to find the camera cable and splice into an RCA cable.

Avinusa Users does your Google Map App. on the Radio Plays the Direction Loud Enough to hear it while the music is Playing?
Also The Thru Car-Play does the Google Map Direction Play Louder?

Mines doesn't its very Low can hardly hear it unless i turn up the volume halfway up.. then the music will be Very loud.. ;-(

I believe there are setting to adjust the volume levels of different inputs. It was not really intuitive to me and required some playing around as it's in + and - DB if memory serves. I'm sorry I don't have the exact area for that, but you might look in the password protected factory settings. I'm replacing my AVIN head unit with a new one this week and I'll let you know where those settings are if nobody else comes up with it in the meantime.

I just checked the manual for the new unit I have and under Factory Settings, there is a setting for Voice: "Adjust the volumes of DVD, System, AV Input, Radio, Bluetooth, and more."

That should do it.

Hello WaveyKat,

There are additional controls hidden in the advanced menu. You have to search the internet for the original manufacture's instruction manual, which also contains the initial access code (like a Bluetooth pairing code). In there you'll be able to adjust a lot of other features on the device as well. I have since upgraded my vehicle to the 13' GL550 and I'm satisfied with the stock command unit.
