Help needed CR-V Navi install
i really do need some help with this project because car electronic is really not my daily thing.
I drive an GT (EX?) Model with subwoofer and standard radio and bought an navigation unit with this part number: 08A40-2N6-400 SSD, which is commonly used in CR-V and Insight aswell.
It was installed in an CRZ already at my guess from the dealership and the owner told me it worked fine but i can only connect 2 cables out of 4 at my CRZ, power and i think antenna is the second one. When i turn on the ignition it worked, touchscreen and tried to find a radio but there was a loud system noise even when i turned the Volume at zero so loud i had to cancel and installed the OEM Radio instead to drive to work next day.
The owner can't remember which cable was connected but he told me he had no cable in advance inside.
Do someone of you have an idea?
