Why did you choose this?

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?

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

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.
