Review on 📻 LINKSWELL GEN IV Android Radio Replacement Head Unit for Silverado and Sierra 2014-2019 Car Stereo 4GB +64GB with Unimeauto Navigation 12.1 Inch Touchscreen, WiFi, BT - TS-GMPU12-1RR-4A by Loren Rindfleisch

Received on 10/25/20. I watched it often on youtube. (NO installation instructions GEN.IV) The most important connection is the telephone USB. The video only shows the installation of the Bose system. Z-Link is the worst phone mirror app. I could only see my phone on the screen once and not more. If you look for questions and problems with system errors from others who have bought the head unit, everything is related to the connection of the phone or the application. Z connection. I ordered/installed a factory DVR from Linkswell. I was amazed at how many great perspectives this simple little camera offered. Unfortunately the app no longer works. Many applications do not work with the system. Linkswell zip files cannot be installed because the USB stick is not recognized by the system. I became an expert at removing and installing the radio and all connections without watching the video. I tried all USB ports; maybe I did something wrong. no Contacted the seller, they were nice and sent me a phone gimbal (Gen IV does NOT need phone gimbals for communication). I can't use it because it needs charging and my USB isn't working. Linkswell, send me an update on Z-Link. Cannot install due to USB. What works? radio, bluetooth/telephone. i love my rock Rock assisted on the long drive to and from Seattle Palm Springs. It is not necessary to see the clock at all times. I hope I found a way to fix the radio. It looks great and once you install it you won't want to go back to an 8 inch screen. Oh, the loading times are long! Do not fully tighten the screws when installing the main unit. Otherwise, the left and right sides will not enter and protrude. Have him drive/fuel all three together. Appropriate top screws are not easy to install - there is no space to securely install the drill. Use the manual key.
