As Tony mentioned at post #4 there was a production
problem through last summer were the Copa was fitted with 2.1 systems because the 2.2 were not available.
I had my Copa delivered in the second week of November 2011 and I was a bit worried about getting the 2.1 system with its post code fault but I was lucky because the production problems were sorted by then.
I think the main deferent’s between .1 and .2 is indeed the post code entry but not having used the 2.1 system there may have been from memory other fixes in the software as well with the likes of Bluetooth and iPod connectivity but this might be just my bad memory.
