i actually had a second antenna around that i was modifying the sharkfin. debating if i want to install this.. the sharkfin cover definitely cannot be removed with it still on the roof, so easy way is to cut it off..

Got it. I'll probably remove the antenna first, just in case I decide to go backwards too.

good idea honestly. the shark fin delete is nice. but theres not much difference doing this and cutting the fin off and applying a blob of silicone...

I did it quickly this morning. Pulled the headliner down, used both a box end and socket 10mm to disconnect (not a lot of room for hands).

I see what you mean about the seals. I like that the new piece sandwiches the existing upper rubber seal to protect the PCB/antenna. It also retains the inner seal on the metal antenna body that goes around the hole in the roof. However, the white piece/outer shell that is removed takes away the outermost, secondary seal against the outside roof. I imagine that the inner seal is quite waterproof, but the outer seal probably works to keep the majority of dust and grime away from the inner joint. There's not much of an area to add butyl or silicone. Maybe I'll add a fillet/bead around the edge. I'm also concerned that the screws are now exposed to the elements, as they could be a passageway for leaks or corrosion to the PCB.

I think that the screws were located outside of the sealing strip, so water intrusion should be next to impossible.

Don't ever plan on using the satellite radio so this is on my list..

Yes true, shouldn't leak to the cabin (at least directly). But it might seep into the PCB via capillary action. I'm not too worried about it. I don't care much about satellite radio, as long as my headliner doesn't turn into a mold fest.


This retains the satellite radio antenna so you're good to go either way!

will definitely make loading my kayak a lot easier..

I wish I could find pictures for getting access to my 2015's headliner area

It's easy. There's 3 pop pins that hold it up in the back, they're plastic and the same color as the headliner. Use a trim tool (or carefully with a sharp flathead screwdriver) and pop them out. To get more space, I popped out the plastic trim around the D-pillars. Didn't remove them completely, just popped them out a little bit. This gives you all the access you need.

I don't subscribe to satellite radio so why do I need a replacement fin anyway? I have duck tape over the hole in my roof but any suggestions on how to repair or fix this? thx

No, you're fine. Duck tape is a great solution

Damn! Did they just tear the thing loose and yank the nut through the hole?

If you don't subscribe then there is no reason to spend a fortune... probably some like this to seal the hole might be more practical.

Something to seal the water out at least.....

For those who have used the GFC delete kit any issues with leaks?? I'm about to do this myself and just want to make sure you still have a good seal. Thanks.

I've had mine for a few months now, but with very little rain in socal (until LOTS today). I will check my headliner etc. in the morning for you.
