Yeah, thanks for catching that. I did mean red and black. And yeah, the solder points were super easy. On my unit its just 4 screws that pop the whole front off and everything is right there.

Has anyone gotten a 64gb or larger SD card working? I tried one and it just kept trying to format the memory card.

I saw someone they got a 128gb flash drive working. I was gonna try an external hard drive, see if that works. If so maybe I'll get a big flash drive

I tried a 1tb hard drive first, not enough power, it'll probably work if you can get in auxiliary power.

Canbus help

Hi, I have buy this universal unit and I waiting delivery...

I want realize android app to display info from the canbus line of my car.

I installed in my car a device that allows me to read the messages in the network canbus.
I spent several months to decode the messages of the CANbus network and at the end, I realized a mobile app that allows me to control the on-board computer of the machine over bluetooth.

My device is made ​​up of "Arduino" + "Canbus shield" + "Bluetooth shield"
I would like to replace this device with this car radio.

The problem is that the car radio have wiring "can rx" and "can tx" but my device is connected via signals "Can Hi" and "Can low".
I need to convert the "can rx" and "tx canon" in "Can HI"​​ and "Can Low".

Do you think I can simply use the MCP2551 transceiver? Do you have the source code of an app that uses the canbus?

Waze works fine. You may have to do some DPI adjustable to get it to look right.

128GB flash drive doesn't seem to work.

Copied 100GB of music to it, the headunit reads it, and I can start playing music, but after about 3min's it gets stuck, and says the device has been removed.

Anyone have anything I can try (Different file system, etc?)? The 8GB worked fine. Both as FAT32

Had the same issue with a 64gb Flash disk. I think something gets reset on the usb bus somehow. Ended up getting a 64gb sd card and have no issues now.

I have the same problem with a 32gb SD card. No problems with a 16gb card. Haven't had a chance yet to thoroughly test the 32gb SD card but I was thinking it may have been defective until now. There are no issues reading from it but it'll display the same behavior as yours if I try to write big files to it.

As I ve said before, Andoid is perfectly papable of reading up SD cards up 128Gb, but you may have to re format them or change something in Android to remove the software defined limit, its a relatively easy thing to do, wikipedia's article on sd cards gives info, google it as well, your ll probably find the thread you need is on xda anyway.

I would be willing to bet it has less to do with the flash drive and more to do with the system trying to catalog 100gb of data. Try putting like 10 songs on there and see if it crashes.

With all this talk about Waze, I was reading about it and it sounds very cool. I was thinking of trying to make a tasker profile that would automatically plot my work every morning if it boots up say Monday through Friday between 7 and 8. Everything I've read says its great at avoiding traffic, so if I could do it automatically, it would be pretty awesome.

Yeh, its definitely something like this...

XposedMTC -- mods for Huifei/RM/KLD headunits

Right now, the mod consists of the following features:

• Change preferred music app from MTCMusic to something else
• Ability to override the default mode switch behavior to include only the sources you want (in addition to Radio and Music)
• Overridden mode switching can add your selected Nav app (in Settings->Gps) to the rotation
• Ability to apply Loudness on boot

This module requires that you first install the Xposed Framework and enable the app_process.

Added the module to the Xposed Repo for easy updating from the headunit.

This is great - thanks :fingers-crossed:

Something to note, the mod does fix the loud issue but the "loud" box is not ticked in amp settings.

NO its nothing to do with that, I told you what its to do with in my post above !!!!!!!!!!!!!!!!!!!!!!!

Yep. It forces loud via an AudioManager parameter. The checkbox is read from the system settings preferences, which gets reset every boot for some reason. It's an aesthetic thing, but I can put it on the list of things to fix for the next release.

Ok know it all... why is the same flash drive working at 50% full without issue?

Your previous post gave no value just stating there is some issue, sort it out yourselves.

Hey all. I believe I have a variant of this head unit built specifically for my chassis of car. I bought it from a US based retailer but I found what looks to be the exact same unit for sale from chinese wholesalers. It's an Android 4.2.2 A9 head unit built for BMW E39 or E53 cars.

Does anyone else have this unit, or are there more similar units to mine that I can get support with? My unit is working pretty well but there are a few things I'd like to fix. I haven't found anyone who has the same one yet.

I'm running a 500GB USB HDD - it needed to use a second USB for additional power - I guess one solution to this might be to use a USB hub if you need additional USB sockets.

I don't catalog it though - I just use folder browsing through PowerAmp

After a little digging around it looks like I've got a HuiFe/KGL-753 which means you guys are all my family from now on. Cant wait to read every post of this thread and get caught up to speed.

Does anyone else have an E39 BMW with this unit? The fitment was not easy as I had to hack out the bottom part of my bracket. My biggest fitment issue is the GPS antennna connector does not have enough room. The one that came with the unit broke as I pushed the unit into the chassis. I have a replacement one but it's going to do the same thing.

The only thing I can think of is some kind of 90 degree coax adapter. Has anyone had these types of issues?

I dont "know it all" I know the basics and gave you the info so you could sort it out yourselves, but there was a solution to your problem and you just ignored it.

Its probably a formatting issue, re-format it and if that doesnt work just use the search function on xda to find out the software solution in more detail.

I dont want to fall out about it, I was only trying to help, I just couldnt believe you totally ignored my post and said it doesnt work.

Unless you want me to come round and od it for you !! Lol

I can't say for sure, but I believe the gps antenna uses sma connectors. There's plenty of 90 degree sma/rp-sma adapters out there.

probably a long shot but has anyone been able to connect a factory Sirius satellite unit up to the HU? I have a factory Sirius module that came stock with my VW unit.
