I recently had the A/C fixed on my car and when I got it back the stereo displayed LOC and will not work. My parents are the original owners and know nothing about any anti-theft system. So I read the Owner's Manual and there is no mention of this LOC "feature" anywhere in the manual.
I've done a bit of searching on the web and found a method that involves holding down either the 2 & 3 keys or the Set key, but neither of these methods appear to work on this model. I suspect those methods only work on newer models.
Anyone know a way of unlocking this that will save me from paying the dealership $40? I wouldn't mind paying if it was my oversight, but the fact that there's no mention of any such system in the Owner's Manual just steams me to no end. I called the GM "Customer Service" line but they just referred me to paying bucks at the dealership. I explained to them that this was hardly fair given that there was no mention of this system in the documentation, and they blew me off.
Alternatively, if there's not a simple known method of unlocking the thing, how do I remove it from the dash? I don't see any obvious joints or screws. I bet the code is either maintained by NVRAM running off a small internal battery or on an EEPROM or FLASH which I can erase with my handy dandy EEPROM programmer.
Thank you for any helpful or humorous comments.
