So I bought a CarPlay dongle from eBay. Installed AutoKit on my Eonon GA2170 8.0. CarPlay works fine and smooth except the charging. It doesn’t charge my phone as i think because of low power from my unit.
Anyway, I bought a powered USB hub and connected that hub between Carplay Dongle and Unit and connected it to my car cigarette lighter socket via adapter to get external power. It charges my phone now along with playing CarPlay but it doesn’t let shut down my head unit when i turn my car off. Head unit literally stays on until i remove that powered hub from cigarette light socket.
Not sure what’s happening. My cigarette lighter socket usually turns off when I turn off my car but in this case both head unit and socket keeps running.
Is the USB Hub also sending reverse power into the HU USB ?
Yes i think so. But I don’t understand why it’s getting input from it and why it doesn’t let 12V Cig socket turn off?
Anyone got any clue?

Am beginning my project to install a 2012 N7, 32 gig, wifi only, in my 2006 Scion xB double DIN as a replacement for the stock head unit. I am keeping the stock speakers for now. I am adding an external amp.
I've done head unit swaps over the years so I know how to open up the dash, remove the existing unit, and how to wire up a regular head unit.
Here's question #1. I am going to use Timur's kernel (using USB ROM for Nexus 7) so that I can use a USB hub and the OTG cable. The OTG cable micro USB will plug into the N7 micro USB port, but the other end of the OTG cable has two plugs. One is a regular USB (female), which I will need to gender change so I can plug into my powered USB hub. The third plug is a micro USB female. Is that third plug needed to bring power or data back to the N7? And if so, what does it get plugged in to?
To power the hub I plan to use a buck converter connected to a dedicated 12v line. The converter will step the voltage down to 5v 3a to power the USB hub. The only thing coming off the hub will be the N7 and a USB 3.0 thumbdrive that will hold my music library.
The second q concerns heat. I'm in S Texas. Has anyone experimented with leaving the back of the N7 off and adding a heat sink to the battery, or adding some sort of insulation, or diverting AC air from the existing ductwork (for when the car and AC are on)? Just looking for ideas.
Thanks in advance for any and all help.

Timurs kernel is old. Use kangaroo rom or any 4.4.2 rom and kangaroo or oxydo kernel in the kangaroo thread there is a power manager app that will allow the tablet to fast charge and turn on and off with ignition. If your worried about heat buy a 12 volt fan and power it up with 12 volt from car. The micro usb female is for power use the cable that came with the n7 Power it with a 2amp or more 5v power car charger(i bought a samsung branded) works great. You dont need a hub if your only gonna power a flash drive. Micro male to tablet, full size female to flash drive ,micro female to nexus charging cable to usb car charger plug.
The GPS WiFi Bluetooth and NFC antennas are all on the back cover so none of them will work without it. So that means no sat nav or internet. I wouldn't worry about cooling it the tablet is meant to function with the back on in a variety of conditions. If you want you could cut a hole in the back there is a copper sheet that is the Nexus's heat sync. Maybe hook up a CPU or graphics card heat sync out a desktop. Or even just stick it to the plastic back its bound to do something.

I have a 2012 Peugeot 308, a Pumpkin ND0286B head unit and a Huawei E8372 USB 4G dongle (with Wi-Fi hotspot mode).
I connect the dongle to the radio's USB port for power.
I've been told by Pumpkin that their units do not support mobile broadband via. dongles, which has left me to require enabling Wi-Fi hotspot mode on the dongle.
The dongle's Wi-Fi hotspot itself is ready 10 seconds after the car is turned on.
However, it takes about 90 seconds before the radio accesses the Wi-Fi hotspot.
Any idea how I can speed this up?
Side note: I tried using a 10,000 mAh power bank connected to my car's cigarette lighter (with an Anker PowerDrive Speed+ 2) via. the power bank's USB PD port and having the dongle connected to the power bank. My hope was that when my car turned off, the dongle would continue to be powered until I next got in the car (so that the head unit can connect instantly to the Wi-Fi hotspot when the car is next turned on) but this system did not work because if I was not in the car for two days, the power bank would run out of juice, and the car could not charge the power bank quick enough to keep it topped up.
Long story short.
Xtrons retractable headunit with usb connectivity issues. Keeps disconnecting usb devices.
Headunit connected correctly.
Usb dashcam and usb thumb drive. Kept losing usb devices. Ohh well... thought not enough power for both.
Bought Tpms sensors... I needed more usb. I got a powered usb hub so I could connect the lot on it and hope to solve the disconnecting issues.
Everything recognised. Not checked if everything disconnects yet.
Problem... Headunit will not switch off unless I physically unplug the usb hub from the power adaptor which is turning off as it is cigarette lighter powered....
Any ideas?
Thank you in advance
Update
If I remove the power adapter from the hub the headunit shuts down normally.
Still usb devices disconnects every couple of minutes.
Any ideas on how to solve this annoying issue?
How about hard wire the hub power into your ignition so it shuts off when the radio does.

Hub is 5v. I am using a 12to5v cigarette lighter adapter.
Cigarette lighter is ignition controlled and switches off normally. The weird thing is that the 12to5v adapter switches off but headunit will not switch off unless I unplug the hub from the 12to5v adapter.....
Hi all.

Have done all nessasary firmware upgrades.
I have tried new cables everything. Nothing works.
Another supplier that sells thses things rekon they have them working in my type of stereo. But mine just reboots.
Can anyone help?

Hey guys
So my headunit that I put inside my 2004 E46 does not support Apple CarPlay from the start.
The unit runs android (10)
I bought a adapter and tried to install the app that It comes with but nothing… no signal.
So the issue seams so be that there is not enough power coming out of the USB port from the headunit.
When I use a splitter and plug the end for power into the lighter usb charger and the data one into the usb dongle it works no problem but it looks ****ty …
Any way or any adapter that I can get this fixed with?
