Default SiriusXM Issue

Due to medical issues, my 2016 Corvette had been sitting in the garage for almost a year. When I started using it in May, I was unable to receive SiriusXM signals. SiriusXM attempted multiple times to resolve the issue via a signal reset. None of this worked. All the SiriusXM channels are grayed out on my radio.

Is there a way to perform a complete radio reset, allowing SiriusXM to resend a signal, and everything would return to normal?

Thanks for your help!!!

Disconnect negative battery cable for 30 minutes, then reconnect. This will cold boot all microprocessor modules. You MAY need to reset seat memory, display, and other settings - seems like the longer the battery is disconnected, the more the car forgets.

It would also be a good time to check key entry and manual door releases before you start.

Leave windows down and hatch open while battery is disconnected for ease of entry.

Bill,

If I remember correctly, when you logon to the XM web site, there is a page that has a button that you can dynamically send the rest signal whenever you want. I would make sure the car is outdoors when you do this. I think the signal goes out within a few minutes of hitting the button, so make sure the stereo is on. Also make sure the radio ID on the account matches what you see on the screen. You can disconnect the negative battery terminal for a few minutes to rest all the computers in the car, but then you will have to reset your windows and all dash settings you had customized.

Ron,

Thank you very much. I will try that this afternoon.

I've never experienced this before when spring rolled around after my Vette basically sat from near Thanksgiving until Spring finally rolled around.

Thanks again,
Bill Radcliff

You can request a SiriusXM refresh signal from your phone, while in the car, here and here.

Yesterday, I disconnected the negative battery cable, which wiped out the old SiriusXM signal data. According to the customer service at SiriusXM, this was due to too many resets and stored data in the car's radio. I had a signal sent this morning and it's working better. However, I am having difficulty with hit and miss channels that I listen to - Fox News, Fox Business and Prime County. Most others seem fine.

I use SiriusXM in our other 2 vehicles with no issues. The Corvette sat in the garage since April of last year because I had a knee replacement with other medical complications. When I got it out this past April that is when I first discovered the SiriusXM reception issues.

Thanks,
Bill

Bill,

Glad your health has improved - that's the most important thing. Hip replacements kept me out of my vette for 6 weeks the first time and 3 the second time. Both manuals. It was hard to look at the car and not be able to drive it...

Oh yeah, also glad the car reboot solved your XM radio issue. I love it when a relatively simple fix solves a problem.

Have fun checking all of your stored settings for seats, radio presets, etc.

Ron

Are your reception issues location based? The SXM antenna is a puck style antenna on top of the driver front wheel inner fender liner so if reception is blocked (it needs a "clear view" of the southern sky) you get poor reception. Normally they are on the roof of cars because it can't be under metal. But Corvettes don't have metal body panels so they can hide it. Other metal or object exterior to the car can interfere with it though.
