I have an 03 LS Premium with the Nav/THX interface. I'd like to see about getting Sirius, however, it wasn't offered in 03. The software on the 04's is slightly different. Since the actual interface is identical to the 04 and 05's, could the software be updated to allow for a Sirius in dash option? Obviously some wiring and a mounted antenna would be neccessary too.

I've asked the dealer, but they haven't been able to give me an answer. Any help here would be greatly appreciated.

I'm quite a newbie, but hopefully soon I'll be able to post some pictures. I haven't done any mods, but I really love my car and always want to learn more.

Thanks
