December 5, 2012

I called looking for the right cable connectors to interface with my stock wiring harnesses and new head unit. The customer service rep found the exact products for my vehicle including optional items to integrate the steering wheel controls. I was able to buy with confidence knowing I would get the right part the first time. Fast shipping, plugged it in and was good to go.
