Have 2017 convertible with shark fin antenna on the trunk. Drove about 1200 miles straight through to Georgia and although I listened to Apple Music most of the time, I swapped to SiriusXM with at times with no issues.

A day or two later, I was driving locally and my SiriusXM went into “Reception may be blocked” and I can’t figure out what it is. Randomly, it does come back on for a few, then shows the blocked message again.

Is the antenna in the shark fin on the back trunk or is that Built in GPS/On Star antenna? OnStar works, built in Navi works, FM works, just not the XM Satellite

Where does it connect to the radio? Is that in the trunk under the floor, or does it connect up front somewhere (where is the SiriusXM tuner located?). Wondering if I could just get an aftermarket antenna and connect to test if it is just the antenna that is bad.

Anyone else have an issue like this?

I had that for a few days on certain channels about a year ago. Software issue on Sirius's end. When I spoke to them, they already knew. Even gave me some money back from my lifetime subscription.

Did you call them?

I did have SiriusXM refresh the signal a few times with no luck.

Ended up going to Best Buy and getting the Magnetic XM antenna, then ordering SMB male/male adapter from Amazon to connect it in the trunk…..as soon as I plugged it in, I started getting XM again…so definitely bad shark fin antenna. Took off shark fin and opened it up and although dry, iit does appear that there were marks on the chips that looked like maybe some water got in. Going to order used one from EBay and replace the insides with one that hopefully works. In the meantime, I can use the magnetic one to get my signal

Cool.
