I realize I'm responding to an old thread, but I have a similar problem.
The interior of my '06 (bought new 6/2/2006 with 26 miles on the odometer

) is stock, save for the odd part here and there I've had to replace over the years, but the steering wheel emblem is original, and as such, all the paint has long since flaked off, so it's just bare metal, which is not super great looking.
I've found that replacements exist on eBay (ex:
https://www.ebay.com/itm/376735155556), but I don't know exactly how to go about removing and installing it without damaging something.
I wonder if it would be easier to get a whole steering wheel and just swap in the better looking parts?
