Ask yourself why you want a newer Navcore first. You will lose EPT functionality and possibly other functions too. 8.351 still is most compatible to the 920.
Having said that, the procedure is quite straightforward:
1. Stay away from the current installation on internal memory but get yourself a Class6 SDHC card.
2. Get the full SE version of the navcore you pursue (9.051, 9.053, 9.101 etc) and copy it towards the card.
3. If you like, download a newer map, copy it to the SDHC card as well and patch it to your device. The SE Navcore however sees the map on the internal memory too.
When you boot with the SDHC card inserted, the new Navcore boots. Otherwise, the old navcore boots.
