Aftermarket radio for 2011 Subaru Impreza 2.5i

[anichin]

I installed Pioneer 2330NEX in my 2011 Subaru Impreza 2.5i. I watched a video for Subaru Crosstrek and there should be cables for the reverse and the hand brake that go to the factory radio. I was not able to find similar cables in my car. Are there any cables that I can hook up for the reverse and for the hand brake that are close to the radio?
Thanks!
