Hi. I have a problem with my speaker on the driver seat side (meron syang parang kuryente sound yung parang nagshort circuit and then mawawala yung song puro gasgas na lang maririnig). Dinala ko sa technician na gumagawa ng speaker, ang sabi sira yung cone ng speaker sa front left side and back right side, so i needed to replace the 4 speakers and so i did. At first okay sila but then 15-20 minutes driving bumalik ulit yung gasgas sound. And hindi na rin gumagana yung reverse camera ng car. I called the technician and he said he will check again but i need to wait until monday to do so. Anyone there with the same experience or can anyone explain what happened? Im not really a techkie person. The unit is GTV. Thanks.
