Sometimes, especially on older stereos, you need to adjust the stereo brightness and contrast specifically for VLine VL2 for CarPlay and Android Auto mode. It will ensure the best quality screen picture for CarPlay and Android Auto.
Adjust the display brightness and contrast to your liking by using the DISP button, if available, or going to the "Factory UI" (for VLine VL2) or "CAR SETTINGS" (for VLite VT2). Once you enter the factory screen, you can adjust the display settings for your stereo's VLine / VLite mode.
Once done, press FM and return to the VLine VL2 / VLite VT2 mode.
