Dealer installed an XM Antenna for my Built In Sirius! Will it work properly?

Just quick background. I bought a new 2007 Prius, PKG 5, and had the Sirius built into the Navigation system. The only problem was that they put the Sirius Antenna on the dashboard, instead of the roof. Of course I got lousy reception because of it. Last week I went on vacation, so I left the Prius at the dealer so they could fix it. I talked to my sales guy and their tech guy who was doing the installation and told them exactly where I wanted the antenna and what type and brand I wanted. I even brought pictures. I just got back this morning from my family's vacation and went over to the dealer to pick up the car. I saw the car waiting for me when I pulled in. I went over to see the installation, and to my amazement, the had installed an XM Antenna, with XM plain as day on the antenna, on my Prius. I can't tell if it is even a magnetic or not which I had asked them to install. I didn't try to pull it to see, that's all I need is scratches on the roof. My Sales guy told me to take it home this weekend and try it out and let him know on Monday. The tech guy won't be back till Monday. It does seem to have better reception then when it was on the dashboard. I am still unsure if using the XM antenna will help or hurt the reception. I am not sure how they connected it, unless they used an adapter.

Beside that, they scratched my dashboard in a couple of places, so they are going to fix that next week.

My question is

1. Is it alright to use an XM antenna for the built in Sirius?

2. Should just have the replace and put in what I asked for.
I wanted either the Terk or Monster small Sirius antenna's that were magnetic.


They did put it where I asked though, right behind the FM antenna.

Please let me know what you think I should do?

 

I am not sure. I can't tell what type of connection they used. I am so frustrated by them not listening to what I asked for, I am going to have them change it out just for the principle of the thing. I feel like I have to be there just make sure they do it right. But, a busy schedule doesn't allow me to do that. I want a magnetic antenna that was made for Sirius, not XM. I really don't want to be unsure if the XM antenna will work or not work. Plus with them damaging the dashboard, that really ticks me off, especially on a new car that is only 2 weeks old.

 

Does that mean I shouldn't use Sirius in my car until it get fixed, or can I listen to it until they get it fix. Or does it not matter, as long as it is connected to the XM antenna it will causing damage even if it is on or off.

I am hoping to get it resolved Monday. I will probably have them replace the antenna, then come back another day for them to fix the dashboard. Because, who knows, when the fix the antenna they might damage something else.

 

I called Sirius and told them what was done using an XM antenna with the built in Sirius in my 2007 Prius. They told me, even with using the XM antenna, they haven't heard of any problems caused to the tuner or reception. They did say older XM antenna's would have problems but the newer one's should be fine. I have no way of knowing which XM antenna this is, old or new or if it is even a magnetic one. It looks like it is stuck on with some sort of sticky tape, which I asked them to use a magnetic antenna, not sticky. Plus on the antenna towards the top is a XM symbol on it. If it had no label on it, and it was an XM antenna, it wouldn't of bothered me, because I wouldn't of known about it. But with the XM on it, it bothers me. I think just of the principle of it, I want a magnetic antenna from Sirius, with no sticky tape on it. I guess, I might have to see what they are going to use.

Are the XM antenna's better?
