Does the unit have a sim card slot? Otherwise maybe its a 4Gb (RAM/Memory) version which you are confusing with 4G internet

that's my unit, Im pretty sure it supports 4G

Hi guys. I bought one of these units (or one very similar, i will post a pic) last year and just had it installed about a week ago. I'm having an issue where it keeps restarting randomly, sometimes 3 times within 5 minutes, sometimes not at all over 45 minutes.
I'm thinking I need to update the software or firmware to fix this issue. But I have no idea how to do that. I just want my carplay to work without the thing restarting. It might be worth noting I have an apple computer and iphone (i tried to look at the dropbox files posted earlier in this thread but my computer wont open them, i'm assuming bc apple)

can anyone here help me? i'm not the most tech forward person, lol

From the picture you showed you have a WIFI version. Is that true? If so you should download the version I have uploaded to GDrive (use 2610pro) you should prepare a USB drive with fat32 format and only have in the drive 2 things
'atcupg' folder, and a file called MCU
Look up how to format a USB drive to fat32 using a Mac

I believe it is just the wifi version yes. i will google how to put a usb to a fat32. in the google drive you provided I can see the file that starts with MCU but i cannot see the 'atcupg' folder, all I can see are these.

after I get these files onto the usb, I just plug the usb into the unit and click a "download" button of some sort?

Thank you for your help also

You need to go intro settings , update and restore , and then update , from there go to img, and click upgrade , after the update is complete , go to the same place and loof for 'mcu' then click upgrade

Please note that after the update you should wait like 3 minutes for all the apps to install

You should take the MCU , and there is a zip file with 2610 name on it , extract it till you find the atcupg folder

did the firmware update, had to change the language from russian to english that was easy enough but ive noticed it doesnt quick boot anymore, it does a cold boot everytime i get in the car.

the setting are set for it appear to be all correct but doesnt seem to want to follow them

any suggestions or could it be a bug in this firmware

also on a plus it is nice to have wireless android auto thanks to the wireless qlink app

Did you update the MCU also?
Try factory restore and give it 3 minutes after ,
If it still cold boot,
Download the config file and it should auto config when you insert the USB

Also, if you did the MCU update, please note, it will reset the Canbus settings, So you should set it up again, some cars have a Canbus Fastboot
