PCM software version

I am the new owner of a CPO 2009 Cayenne S.

When I purchased the vehicle I looked at the PCM software version to make sure I had the latest software and maps. It read 1.40

I remembered reading there had been recently an update for PCM3 to 1.44 so I asked the dealer to update the software, which they did at no cost.

After a couple of visits, as they had to order the update for my specific MY, the update is installed.

It now reads version 2.21

Is this the current one? Have they uploaded the wrong vehicle software?

The new update erased all previous and stored destinations, all radio and sat presets, and also defaulted to UK units and language. I am not sure this was supposed to happen.

Any thoughts?
