Review on Metra 70-7301 Radio Wiring Harness for Hyundai and Kia 1999-2008 by Benjamin Saric

This is the correct wiring harness for the 2003 Hyundai Sonata LX Tape/Recorder/CD Player. The instructions say to connect the blue/white wire (turn on the amplifier) to the "secondary radio remote output". The cheap radio I bought as the car is over 10 years old didn't have such a socket. The solution is to connect this blue/white wire to the blue power antenna wire and the power antenna wire on the main unit. DO NOT order this harness: http://www.amazon.com/gp/product/B000KL30VA/ ref=oh_details_o01_s00_i00?ie=UTF8&psc=1 It does not have the blue/white wire mentioned above and will NOT work.
