the systems for the 4inch screens started arriving a couple of days ago so some new issues and some that might have been addressed before are coming up ; there are 3 issues that are really bugging me and at least one of them is related to the 4inch screen system hopefully someone can pitch in:
1.radio console/music player: since the stock 4in screen is not touch, it is not passed-passed-trough ike the 8in system. the oem usb input is shown as a (♫) symbol and there is a (sync) symbol which seem to be linked, however i dont know the actual function of this option. They will play music from a usb connected to the oem usb port, but it only plays the last file that was playing in my stock radio with no option to browse the usb library.
b)the music app from the tablet will play mp3 files from a usb plugged to the tablet usb port but there is no sound, the radio sound overrides this app, .the only way to get sound is if i go to the radio console, select the (♫) option and press play (with no usb plugged in the oem usb port) , then i will get sound from the music app but only for a split second before the tablet sends me back to the console screen automatically for no reason, it just doesnt let me stay at the nusic app)
2. bluetooth: i seem to be getting two bt signals, the sync signal and the tablet signal. the sync signal works but its not displayd anywhere on the screen so i can not connect to it.. the tablet bt is working but i get no sound output. (or the bt
sound doesnt override the radio sound)
3. reverse camera flickers and only shows the actual reverse image for fractions of a second at a time, i already found another 4inch user with this issue
