My 2008 came with a color matching small hump on the trunk. Do all of the newer S2ks come with this satelite radio antenna? If not, is this a Honda item or aftermarket?

 

its an available option from Honda for XM radio

 

dealer added, fortunatly who ever added it had it painted as they all come from Honda in Silver(not sure why).. It would be an OEM accessory

 

Mine has the option as well. Yours is the only other one i've seen. I don't think it was a big seller. If I drove my car more, i'd pay to have it work.

 

I was just about to post about this. Does anyone know where the smaller edition Sirius antenna can be placed on the inside of the s2000. I tried the roll hoop but I get static and cuts off. Definitely do not want that thing outside anymore.

 

I put mine on the dash, in the middle right under the windshield. My reception is great

 

I have mine there too, right between the vents for the windshield. Works perfect and is pretty well hidden.

 

I just moved my antenna to the top middle of the windshield, right above the mirror. The antenna is upside down and reception is cutting out all the time.
I don't recommend this position. I will try the dashboard and keep the antenna right side up

 

I put mine on the drivers side at the top of the windshield. The XM antenna being magnetic sticks perfectly and hasn't budged in the 10 months I've had it. I fed the wire down through the gap by the convertible latch, into the A pillar. No interference or issues.
