If you can find anyone with Module SM059 software (Faultmate), they should be able to (a) reset the security code, and (b) reprogram the language. Best bet is an Independant if you don't want to pay Stealer prices.
I've recently bought a 2004 4.4 Vogue with an integrated telephone. I've tried to put in a SIM card but keep getting "No Network". Is there anything obvious I need to do to get this working?
