SiriusXM radio stopped working. No signal!

I'm guessing any repairs would be covered under the extended warranty (the devil's in the details, of course), but the initial diagnosis isn't.
$100 seems to be typical for the diagnosis fee.

 

they covered mine under the warranty. They said the Antenna was bad.

 

Its the crappy antenna that Toyota put on the Prius. Mine as been good so far.. But it has been starting to cut out again. Might be time for that aftermarket antenna.

 

the external antenna on the roof.

 

Well, I had the same problem (total loss of SiriusXM). After reading this board and applying my years of experience as an electrical engineer, I unplugged the antenna cable from the unit under the drivers seat, re-plugged it in and it worked! Probably gunk buildup on the terminals. And I thought 4 years of multivariable calculus was a waste

 

I had the same issue. Retired the reset, talked to Sirius CS, and nothing. They told me back to the dealer.

They told me they needed to replace the wiring bundle, and that the part would be $375+ tax! That seems a bit absurd.

Has anyone done this? Am I better off trying an auto electronics dealer?

Of course, the warranty is now prob expired, though it was still in force when they gave me that quote

 

If the warranty was in force when you took it to the dealer, they should repair it at no charge.

The radio on a Prius is very easy to remove and replace. So it's not much effort to remove the radio, unplug & replug the antenna cable.

The antenna isn't too difficult, either, but you do have to separate a little headliner to do it. I'd definitely go to a reputable car audio shop. There are good ones and bad ones. The Toyota dealers tend to replace parts without trying to fix anything, and they have high labor rates. I avoid them.

 

I just replaced the "Antenna Assembly", part number 86960-47011 on our 2011 Prius, which exhibited pretty much the same symptoms that Infini has reported. It completely solved our satellite reception problems. As a degreed Electrical Engineer whose father was a high school auto shop teacher, I enjoy doing my own repairs, so it was no big deal to pry the rear of the headliner loose (assume that the plastic pins will break - because they will), and remove the antenna assembly. (There are a few useful tips you should know first, but it's not too difficult, really.)

When I took the "Antenna Assembly" (i.e. the black base that the AM/FM antenna screws into) apart, it appeared that the metal of the patch-antenna for the satellite system had flaked away around the edges, even though there didn't seem to have been any water intrusion into the base. Knowing what this usually does to the tuning of 2.3 GHz antennas, I replaced it, with a little encouragement from our favorite Toyota mechanic.

I can send you pictures of what the bad and good satellite antennas look like, if you want.

 

Sorry for the delay, I thought that I had things set up to let me know if/when someone responded to my post. Here is a picture of the BAD antenna base from our 2011 Prius:



The "patch" antenna for the satellite receiver is the blackish square on the right. Here's a close-up of just the antenna:



And here's what the antenna on the NEW antenna base looks like:



See the difference?

Again, there were no signs of water intrusion or other mechanisms for erosion of the patch antenna, but when I opened the case, it just looked "black and furry", as though the conductive plating of the antenna had flaked away from the ceramic substrate (the beige-pink stuff underneath the metal antenna). When I blew on it, the black flaky stuff on the patch antenna all disappeared, leaving what the picture shows.

Hope this helps!

 

my is doing the same thing on the phone with street toyota there telling me over $ 700.00 to fix it

 

Use Craigslist to find a wrecked Prius that's being parted out. Way way cheaper. Probably $25 gets you an antenna and there's probably some other useful part you'll pull.
