Hello gbest!
I changed the battery on my 2003 9-5 aero and got the dreaded "Radio Code" on the SID. If I plan to keep the stock HU, which I do, it looks like the Tech II head unit remarry procedure is my only option.
I'm in the South End, Boston, but can cruise out to meet you where convenient. Any chance you can help?
Thanks!
Dan
