It would appear that someone has had success in installing the Vauxhall/Opel Nav disk on their 16 Bit PCM 1 in a 2001 C2.
He has posted on the Renntech site that he bought the 2005 disk set from a German dealer advertising Vauxhall/Opel GB/Ireland 2005 disks that are PCM1 compatible at £125 on Ebay. He says that there was no requirement to update his PCM and he even gives the CD part number which is T1000-8039.
I have attempeted to contact him and gain more information regarding the dealer. RB
