Shark Fin Antenna Adapter, SFA12F

I have a 2011 Toyota FJ Cruiser without JBL and I replace the stock radio with a Pioneer AVIC 5201NEX and a SiriusXM SXV300 sat radio. The Pioneer and the SiriusXM radio came from Crutchfield, the only place to buy this kind of stuff and be sure to specify JBL or non-JBL otherwise the cable harness will not be right. And even then the Crutchfield support is awesome and they will help you out. Anyway, Sirius claims that you cannot use the stock sharkfin antenna and that the included antenna is much better. If I place the included antenna right behind the windshield then I have perfect reception driving north to south, the other way around it drops the signal every couple of minutes. So I bought this cable. It is a bit too long for what I wanted to do, but it really works. No drop-outs at all. The only thing I will caution about is that the plug on this cable that goes into its counter part on the car side is slightly too big. At first I thought I had the wrong part but eventually it slid into place. Pull it out and put it back in a couple of times each time making sure that the pin did not bend. Eventually it will go in smoothly

Expensive, but worth it to me because it allowed me to use the factory XM antenna when I upgraded to a Kenwood DNR1007XR in 2013 Tundra Platinum crewmax with JBL & navigation. The cable was crazy long for my application, but the bottom line is it worked & now I don't have to route another XM antenna. I also did not have any of the issues others have mentioned with the adapter plug end being hard to engage. It snapped in very easily.

I installed this in my 2011 Toyota Sienna while installing an aftermarket radio with sirius xm. This connected perfectly to the factory antenna connector behind the dash, and connected to the sirius xm receiver. However, the XM radio was unable to receive any signal. Using the included XM antenna instead resolved the issue. As my factory antenna worked fine prior to the replacement, it can only be this adapter that fails to work.

I purchased a Pioneer AVH-2550NEX to replace my 2013 Toyota Tundra OEM head unit where the SiriusXM would cut in and out. The SiriusXM module came free with my new aftermarket radio so I figured I would try and install it using the OEM shark fin antenna. The adapter worked and the radio played perfectly. From the looks of the two plastic connectors, it seemed like they would not fit together, but if you line up the internal connectors to how it matches up and push it in with a little force, it fits just fine and works. Would recommend for a 2013 Tundra.

Mine was a dud 2 times. Gave up and installed new antenna

This was the only adapter that would fit teh Toyota sharkfin connector on a relative's van. The reason I am giving it 3 stars is due to VAIS tech supports unwillingness to help. The cable was too short to go from teh Sienna's rear tailgate to teh back of the HeadUnit where the SAT tuner is located. When VAIS tech support was contacted, they kept insisting that the 12Ft cable is sufficiently long and shoudl be fine for the VAN. For a car, yes and for a van where the connector is sharkfin connecter is located close to the headunit or under the fron seats, it will work. If your connector is on teh top of the rear tailgate (as in Tooyota Sienna 2011 and up), this is 5-6 feet short.

This is one of those items you can do without, but it's a great addition to your DIY radio project. There are several points to make which may be helpful. (1) This was for a 2011 Prius II which was satellite ready. This is important since it means this particular vehicle has a factory installed antenna system which can be utilized to get decent satellite radio reception. (2) You can install a satellite tuner without using this product. You simply run the magnetic antenna to the outside of the vehicle and stick it to the roof. (3) If you prefer (like I did) to avoid using the outside/after market antenna, then this product will work for you. (4) This next point is very important. THIS WAS THE WRONG PRODUCT FOR THIS VEHICLE. We had to return this and exchange it for the SFA12M. I repeat: SFA12M.. (5) We contacted VAIS Technology, and their staff was extremely helpful in exchanging the product. And I might add very quick in shipping out the new product. (6) I can only speak for this particular model vehicle. The connection for the SFA12M was between the front seats. The center console was easily removed with 5 bolts (10 mm socket) and the already installed and pre-wired satellite module was obvious. Yes it is expensive, But if you want to use the system already in place on some Toyota models and avoid the extra wire and antenna on your roof (that comes with the tuner), this is the answer. It is always a pleasure dealing with Amazon, but even more so with Amazon's partner - Vais Technology. Recommended.

Worked perfectly on my 2011 Tacoma. I searched for 6 months to find one of these. No more signal drops on my new head unit!

Works perfect for my 2013 Toyota 4Runner. It’s the only cable that works if you want to retain the factory SiriusXM antenna.
