I have a '93 W124 that will soon be ready to sell, and it has the OEM MB/Motorola phone in the armrest. When you turn it on, it says "locked". Unfortunately, I didn't get any manuals, records, etc. with this car, and I know just exactly zero about the OEM cellphone system. What will it take to activate this phone, and/or what do I need to scrounge up in terms of information to get it done for a prospective customer?

Thanks a ton...
