2015 Yukon Denali Satellite Radio No XM Reception

[reath1]

Did quite a bit of searching and haven't found much. Last week we started getting the message "No XM Reception"- "Signal May Be Blocked".

Saw instances of the antenna leaking on the models with the painted cover but ours is black.

Had them send a refresher signal but no luck on that either. FM reception is still working fine.

Any ideas?

Thanks

Anyone?

i think people had problems with corroded antenna wires as well could be your problem and FM radio antenna is on rear quarter glass

I read several "corroded connection" posts but the ones I saw were associated with the painted covers. Not sure what the difference would be though. FM reception is perfect. It's just the XM that has issues. Thanks.

I am am having the exact same issue with my 2015 GMC Yukon Denali, were you able to get this resolved? If so, what was the cause and how did you repair it? Thanks!

The cause was the antenna. Change it with the correct one and you'll be good to go.

Thank you! I had to replace the engine temp sensor and unhooked the battery. Once I got everything set and started up the truck, the XM Radio was working again. Thanks for letting me know what my next step will be if this happens again.

I had the same issue. After much research... and don't forget.. youtube is your friend.... I decided to order
a replacement antennae.... followed instructions from youtube....and did the replacement in about 30 mins...and bingo.. everything is working fine. Water gets into the antennae and corrodes. After I loosened the bottom retaining bolt under the antennae.... and started to lift it... water just poured out from the inside.

My SXM antenna had water retention & corrosion problems which was causing very weak SXM reception. I ordered a new antenna and used silicone sealant with the gasket already on the antenna to keep water from being admitted underneath of the antenna. I now have SXM reception!

I had the same issue. The old antenna had a drain gap in the rear of the gasket so water was running underneath of the antenna with no place to go. The new antenna had the drain gap in the front and I was concerned that water would be blown into the gap so I used black silicone to seal the entire gasket before mounting the antenna. It's nice to have great SXM reception again!
