SOURCE: How to unlock radio in 2005 saturn ion

It may be complicated, depending which radio you have. UC1 or US9, US8. The owners manual should have all the info you need. You do have the radio code, right? If not...you will need to visit the dealer. If you have the code, the radio must be on for 1 hour and then it will unlock when it reads - - - - , and you can put the code in. Its not your girlfriends fault. ; )
