PCM Version

Recommended Posts

I am not an expert on PCM but this is how I understand it. There are 2 versions of the PCM

PCM 1, which is easy to identify immediately by just looking at the unit. If you have a 6-digit keypad then you have a PCM 1 package. However, to confuse you a little more there were two versions of PCM 1 – an 8-bit processor that ran from 1998 – 2001 and then a 16-bit processor from 2001 until 2002. To check to see which yours is you will need to slip out the Navigation processor (the unit that you insert the Nav CD into) to ID the serial number. This is done by removing the two strips at either end of the processor (these just flip off) and inserting audio removal prongs into the two holes to release the unit so you can pull it forward

8 Bit serial numbers (found on the rear of the unit) will be either 996.642.122.00 to 996.642.122.02

16 BIT will be: 996.642.122.03

PCM 2 is different not only in looks but in technology. The immediate difference is the positioning of the push buttons on the unit, a 10 digit dialling keypad, no phone card slot and absence in the dash of the CD processor. PCM 2 also uses what is know as MOST technology to operate which makes the interchanging of these two units not an amateur installing option.
