FYI, I had to replace the antenna mast on our 07 XKR after it caught the edge of our garage door and bent it. FYI I found a correct replacement mast for $15 on eBay, and did it myself. Anyway, I did a write up with photos, and you can find it at https://db.tt/Q92tYTd5

 

Very thorough writeup! I will say that when doing antenna work, you should be very careful to make sure you have a good seal on the power antenna. On my '97 Lexus, I replaced the power antenna mast but one of the o-ring seals did not seat properly. A few months later, I noticed I literally had a trunk full of water! (OK, maybe not the whole trunk but definitely the wheel well where the spare tire was had several inches of water!) Lesson learned!

 

Memory and only memory says you wiggle it off. As in wiggle it side to side til it releases. MEMORY says it has a grommet type bottom with a groove in it that holds it in place to the sheet metal. Did I mention MEMORY says this. I've been there and changed out the mast on my 07 a year and a half ago and bought a ?? fifteen buck mast off Amazon? Ebay? got me where cheap and it works fine now. I unplugged the motor shortly after fixing it 'cause I now have Sirrius radio and a lot of CD's. Don't need no stinkin IPOD connection, CD's work just fine.
