Mine was crappy from day one. I drive a 2012. It always loses it under overpasses. So I start excelling at taking fast u-turns ...
Did they replace it with another shark fin, or a different model antenna? I just signed up a few days ago and the reception is horrible. Unusable. My neighborhood has some established trees, but we never had any issues with my wife's Accord.
It's another shark fin, but I can't say it is an OEM replacement. The new one is black with a rough finish. I had to refer to some photos to verify the original was also black, but have no way to verify if it had a rough or smooth finish.
I have posted in at least one other Serius/XM reception thread about this experience. They had the truck for 3 days, ran every test known to Toyota and Serius/XM before settling on the antenna as the culprit. It may have been a lucky stab in the dark. My wife drives a VW and it has excellent reception and my T4R now has as good or better reception. As already stated, I now get reception in the bowels of the parking garage at my office. Before the fix I would lose reception on the highway out in the middle of nowhere and around town it was useless.
Did they give you an itemized receipt with a part number? Mine isn't under warranty anymore, but I wonder if it's something I could order the part online and swap out myself.
I looked through my records and the service order does not list the part number. My copy is not the complete service ticket since this was paid for by Toyota as an out of warranty repair. The dealership had to forward the repair order to HQ. Sorry I can't help.
If you have record of taking the vehicle in for this repair during the warranty period and they could not fix it, or "no trouble found", escalate to HQ. That's what I did after three NTF's during warranty. HQ authorized the repair and suggested I take it to a different dealer. I took it back to the same dealer to give them one more chance and, when they saw the authorization from HQ, jumped all over it.
No activity here in a while, but....
2012 limited, and have had this problem for almost two years with it slowly getting worse and worse over that time. Really bothered me since I’m a fan of the XM, use it for traffic, and just wanted it to work.
Been in and out of the dealership service department and checking multiple online forums (not just this one but all makes and models).
So it seems to be a relatively “known” issue with Toyota XM antenna across the board - they break down over time.
After a quick search, found an adapter for about $50 and then an external antenna replacement for about $20.
Perfect signal since...
Dealerships latest guess was to replace the whole receiver for about $2k. Glad I pressed the issue and kept checking!
Happy to supply instructions, parts, etc if needed...
It seems like a good number of folks mentioned this starting up over the last couple of months. One person pointed out that there seemed to be an entune update around the same time. possible culprit?
but a lot of other folks also mentioned the sharkfins have normal breakdown.
Has anyone replaced the antenna but no improvement or doe the antenna replacement always seem to fix it. This would rule out the software update.
Cyberwhale - I created an account just to thank you for your info. I bought the antenna and adapter you posted and it immediately fixed my issues. I did mount mine on the roof near the shark fin and run the wire through the gap in the hatch door, through the weather stripping on the hatch and under the carpet around the third row if anyone is interested. No new holes required. Took 45 minutes.
Two people in the past month or so have asked, so let me post the full rundown here:
My Equipment:
2012 Limited Edition with JBL sound. No customization done to audio system
Isolating the issue:
As I mentioned before, I had been in and out of the dealership trying to figure out the issue. I was getting a "No Signal" error on the radio.
At my latest dealership service appointment, they told me they think the XM control unit is faulty and I need a new one. Not wanting to drop $2k on the issue I dug in myself and noticed that when I unplugged the antenna from the control unit, my error switched from "No Signal" to "Check Antenna". I ordered a replacement (refurbed) control unit and was getting the same errors. Ordered replacement antenna and problem solved

Details:
For me, that control unit sits under the front passenger seat.
All the connections are facing forward, so you can carefully peel back the carpet (with the seat moved all the way back) and expose them. The antenna dongle is the gray one (smallest). I swapped the shark fin for the new one and ran the cable under the carpet, up the a-frame pillar and behind the dash. My new antenna sits next to the front passenger speaker and is held there with a little double sided tape. Yes, I could have put the antenna on the exterior, but I didn't want to make any holes or deal with waterproofing, and the new setup is strong enough that the windshield doesn't cause any signal loss.
I also didnt replace the shark fin, because: fool me once, shame on you; fool me twice... OEM fin replacement is ~$250+ for a part we know will deteriorate again. No thanks...
Unless you've made some major electrical mods, then I'd go to the dealer and let them sort it out.My radio is shot, The XM signal is not good and when I connect my phone Note 8 to it it reboots constantly until it doesn't turn on anymore. My 4 Runner is a 2019 and only 3 months old.
