Hi all, third day into the wonderful world of Lexus, & could do with some help. The reversing camera display on my 2110 RX 450h, shows the camera image just fine, but, about 50% of the time, the guide lines consists of one green curved diagonal line. Is this normal or a hopefully one off warranty call. And while I have your ear, my iPhone connected perfectly for calls, but I can’t work out how to get my audio library to link to car. Thanks for any advice.
