Customer Q&A

7 questions already asked

Do I need this adapter for my 2007 Ram with the Kenwood DMX47S unit? I know it recommends a kit when I add the unit to my cart but for instance, I don't need the steering wheel controls. I don't have any on my steering wheel.

You would need that antenna adapter in order to continue receiving AM/FM stations when you install a new head unit because the input plug differs between factory and aftermarket radios.
[ ARIELLE H  Jul 19, 2022 ]  Staff
how long is this cable, will it extend my cable.?
[ Robert  Feb 15, 2022 ]
1 answer
its about 6" but its not meant as an extension, as you see the male end is different from the female end, this is an adapter to allow an aftermarket radio to be installed while maintaining the factory antenna
[ jim  Feb 24, 2022 ]
I have a 2007 Dodge ram 1500. Does this coax antenna fit the new radio for Sirius XM?
[ Jimmer  Apr 01, 2021 ]
1 answer
This adapter is for the FM antenna and will not work to adapt the SiriusXM antenna. At the time of this post, we do not have an adapter for the SiriusXM antenna. That may change in the future and we recommend contacting an advisor by calling 1-800-324-9695 to check

Will this fit a new body style 2007 Chevy Silverado with a pioneer avh- x2800bs? The adapter that came with my scorche kit doesn't work
[ Wesley1293  Dec 14, 2016 ]

For additional details on fit or installation please contact an Advisor by phone (1-800-324-9695) or online chat. They will be able to pull up your vehicle and give you the details on if this will fit and what you will need for an installation in your vehicle.

I can't seem to get the 40-CR10 to actually reach the antenna in a jeep wrangler 2006, it's about 2-3 inches too short. Is there something that can extend it?
[ jcotar  May 20, 2016 ]
3 answers
You can get extenders from Crutchfield.
[ JEFF  Jul 12, 2019 ]
Maybe you can reroute the wire a different way from where the antenna enters the Jeep to the radio.

Installation: appears the existing factory to adapter connections are male to male. Do I have to remove the existing one?

PPush fit into groove around speaker enclosure.
[ STEVEN W  Aug 02, 2015 ]
THe gm oem head unit has a male connector inside. This adaptor emulates this.
[ STEVEN W  Aug 02, 2015 ]
Just plug and play. Nothing to cut or remove. Just plugs right in
[ FRANK  Aug 01, 2015 ]
In case I was not clear...the cable converts the Nissan/Infiniti cable into both a male and female standard end
[ CORY  Aug 01, 2015 ]
If you have a Nissan/Infiniti antenna wire, this will plug into that wire and it had two tails, one is standard female and one is standard male...most likely you will use the male end to plug into your new head unit and cut the female end off or just leave it hanging
