Have a 2011 GS that has very poor radio reception on syrius channels. Continual fade in and out. Ant fix for this

That's interesting. I was thinking the other day that my Corvette seems to have a better signal than my 2010 Malibu (with the ugly black XM antenna on it).

Sirius antenna is not under the windshield, it's in the outside mirrors except for 2005 C6s.

My 08 vert has this exact issue too. I thought I saw some fix somewhere in here, but cannot find it right now. Will keep looking.

Thank you I forgot.

Same with my 2009 vert. Much worse than my Sky was. If there's a fix, I'd love to know it.

Ditto here :d

funny you bring this up. Xm had a free trial this past weekend and reception in my GS was WAY worse than my Jeep or Ram. I had been thinking of getting it for the Vette but after hearing the crappy reception I decided not to. especially since it only gets driven 8 months out of the year.

I sometimes lose reception when I pass a truck. I think its because corvettes sit low and the antenna is located on the side so the signal is easy interrupted.

Hmmmm. I get no fade whatsoever. The only time I run into minor loss of signal is when in the mountains and the mountain moves between me and the satellite location, or occasionally in larger cities with tall buildings. Mine is an '06. They didn't change the antenna type or location (DS mirror) in later years, did they?

I understand that "ground repeaters" are used in metropolitan areas to keep the satellite signal strong enough for most areas. On the old add-on Sirius Starmate radio in my wife's truck, it had a screen you could bring up to see the satellite and ground strength levels. In weak areas, it was all ground signal reaching that unit.

I get it with trees now. That never happened with my Sky that had an outside antenna. It almost has to be the antenna in the mirror that is the cause. Seems to me anyway...

I don't think its a likely cause but, you could start by checking the 2 antenna connections at the XM Tuner module.

It's located under the carpet behind the driver's seat in a coupe, and under the waterfall in a vert.

The orange/yellow one is for the Sat and the green one is for the ground-based repeaters.

Keep in mind that the XM Satellites are parked in stationary orbit above the equator, so any large obstruction to the south may disrupt service if a ground repeater is not nearby.

Changing tuners to a SIRIUS module gives you access to their satellites that are in geo-synchronous orbit running from pole to pole. This means there's usually one 'directly' overhead providing better reception most of the time. Not to mention better audio quality.

Comparing the reception in the 'plastic' C6 to any other larger metal-bodied vehicle is pointless. Personally, I prefer the hidden antennas to a wart on the roof/trunk.

YMMV

My SiriusXM reception is pretty good, meaning that I don't get loss of signal. The only time that occurs is when I'm driving on (usually mountainous) roads with a tree canopy that completely covers the road.

That said, the quality of the SiriusXM signal is horrible. I'm thinking about canceling it.

Reception is no better on my wife's '13 Caddy ATS. It has the "ugly" external antenna on the rear of the top.

The antenna needs a clear view to the satellite. I've noticed that when large trees are close to the road my signal is weak or interrupted. It has marvelous reception in the desert...

My reception is hit and miss especially when hills or mountains block signal. Pandora may be taking over for me. I can drive through a tunnel and not lose reception.

I know that Sirius and XM are one company but they use two different technologies in different areas. The Corvette uses XM not Sirius. XM in certain areas uses ground repeaters not satellite. My MB with Sirius has better reception in the same area than my Corvette. Other than an electrical connection or bad receiver it is a fact of life Sirius at least in my experience is better than XM. More outages on XM.

csf

Me too. Perfect on the highway, but once riding on the heavily tree lined secondary roads to my house the satellite radio is basically gone. Worst reception I've had in any car.

My free trial is over next month. I won't renew unless they give it to me for a very reduced price.

it's too bad that GM couldn't of used the rear OEM spoiler as a mid antenna to compliment the (2) side mirror antennae

The rear spoiler looks better than the 05 wart ever will.

Maybe someone can come up with a way to get an antenna in that spoiler

not08crmanymore

Move the antenna to the highest point on the car and problem solved.Yes,you would need to get an outside xm antenna and run it....I did that on one of my 08's and it was night and day.

Where do you plug the outside antenna to ???
