Hi, I have recently replaced the Symphony 2 with the 2+, I used an RNS-E harness, but when I connected the radio it did not turn on, we had to connect a power point to the fuse box, this does not look good.
When turning on the radio does not turn on, you have to do it with the power button.
I think this can be corrected by properly using the harness pins.
Thanks for the help
