Since finding and resolving this 2007 TL Wiring Harness Connector to XM Radio Antenna problem,
my SiriusXM reception has had NO interruption. I will report back — IF this changes.
Unfortunately, AcuraPartsWarehouse.com denied my RMA of the UN-USED parts !!
I DO NOT Recommend this Vendor.
Small California operation, that sources via Parts Departments of Acura Dealers.
In order to process your RMA request for order VAAxxxx, please review the information below.
We are sorry to inform you that your request has been denied because of the following reason(s):
The part(s) is non-returnable items due to it being, but not limited to:
After a month of XM operation (re-plugging loose connector) ...
I noticed loss of signal “Shadowing” around tall buildings (over 20 stories), like before.
Since I am only 15 miles west of Chicago ... the local repeater XM terrestrial signal has normally filled these spots.
—
So it appears the S-band pre-amplifier (within the XM antenna) may have failed.
I swapped the original XM with the Acura replacement this morning.
So far, no loss of signal other than local parking garage (expected). I will continue to monitor.

The instructions and photos for removing (and re-installing) the XM antenna are very good.
A few points to note:
1.) A standard 17mm crescent wrench is very difficult to use for removal (and installing nut), due to clearances.
A low profile socket, as shown with instructions, is definitely BEST method.
There is little room above headliner and a couple of sharp metal body joints.
I had to use two fingers to start the 17mm nut on the XM threaded stud (patience, patience, no coffee).
2.) The antenna lead from the XM radio had no slack (factory wiring harness problem? ) for plugging in the XM antenna lead.
I have big hands ... so it was a challenge to disconnect and then re-attach the plastic locking connector for coax.
Take your time ... option is to remove headliner (ugh).
I have come to the conclusion that this issue is KNOWN by Acura suppliers (Entertainment/XM Sirius System).
The problem is FCC allocating adjacent frequency bands to Cellular/Mobile Service providers (and other users),
especially the Terrestrial XM repeaters in urban areas.
The Acura XM receiver is 2005 design and Lacks higher filtering required when high power adjacent services are present.
In addition, InterMod is a another issue (mixing/subtracting).
I agree, White makes more sense because cars are harder to cool in the summer than they are heating in the winter.
But I have a black car, and recently noticed a slight bit of discoloration in the clear coat on top. So I was thinking about putting a cover on top as well.
I thought about White.. but that may be too much of a contrast? So I thought about gray...
But if I get gray, do I want to buy a matching XM atenna?... OR just completely remove the antenna because I have the GROM .. I do not use XM radio
So I could just cover the hole entirely and skip the antenna.
Gray and White top on a black car (Avoiding black for Cooler Summer) it will likely be Darker than my example below, if you see that llink above =)

It is also easier to play with the vinyl, and get it to sit right if it's warmer out. If you're worried about the black attracting heat, then why do they even make black cars? Not a vaild point.
