Help with Aerpro Harness

Hi All,

I have a 2013 Kia Sportage Platinum.

I have purchased the following items to install an aftermarket headunit to gain Android auto;

aerpro-apa47
AERPRO-CHKI14C
AERPRO-APP9PIO8
aerpro-fp8011
AERPRO-APRTK2
PIONEER-SPH-DA360DAB

Attempted install and found that the steering wheel controls won't work and there is no sound coming from speakers.

I've triple checked all connections and I believe I have everything plugged in correctly.

The CHKI14C I am assuming is the issue. Have I purchased the wrong item for my car?

Or have I missed something?

There is a blue/white wire that is not connected from the AERPRO-CHKI14C. States amp remote wire but not sure if I need to splice it in somewhere.

Thank you.

I have attached the manuals for the factory headunit (lan8900 – has optional 24pin TYCO AMP and therefore no connector B within the 26pin power connector) and for the AERPRO-CHKI14C (CTSKI009.2).
