Stereo & Electronics - Where to get new Factory 12 disc magazine?

I need another 12 disc cartridge, GM dealer tells me they have to order a whole new changer at over $400. If anyone knows where to get or has one for slae let me know.

Your dealer is either too lazy to look up the part number or too stupid. The part number for the cartridge is 25678545. You can also find the original Pioneer cartridge online (the GM changer was made by Pioneer). The Pioneer number is JDT1212.
