Plug&Play, yes, really!

October 27, 2009

Bought CTHO-03 to fit a new Alpine dash am/fm/cd in place of the 2007 JK Wrangler factory radio. Worked from the first time, i just followed the wiring instructions that came with the CHTO-03. Balance, Fade work fine but the independent volume control for the factory subwoofer is lost now. General sound quality is same as the factory radio.

Great product

September 19, 2013

I needed that box to change my OEM radio for an after market. Installed on a Jeep Grand Cherokee 2008 with Boston Acoustic audio system. Easy to plug, very convenient, and sound is very great.

Great wire harness

October 20, 2013

Great harness to ease the installation of a after market h.u to a factory amp. Install took less than 15 minutes and was as easy as 1 2 3

Great value

September 28, 2015

Due to my vehicle (07 Dodge Nitro) which has a factory pre-amplified system, it did make wiring together a little difficult but, I took my time and read all instructions several times as i wired it together and I was successful in installing this correctly. The reason I gave a 3 star on the ease of use is only because of the above (pre-amplified vehicle) The instructions for none pre-amplified systems looked a whole lot easier! Please don't be discouraged by this review. This harness works well....

I chose to order this interface to upgrade my jeep stereo rather than purchase locally for a much higher price.

Would still keep steering control?

Best Answer: Hello,

No. You will also require the Axxess ASWC-1, Universal Steering Wheel Control Interface.

I saw the video on how to update the ASWC module online. Should it be done prior to install ?
Can it be done after install ?

Best Answer: Doesn't really matter when you update the ASWC module as long you have access to the module's usb port. You will need to follow the identification procedure after the update though.
