Sat Nav SD Card Upgrade

[SHIFTY]

Anyone know what the difference is between the AM sat nav SD card upgrade CG43 10E88 AL 010 11605 A8 and a CG43 10E898 AK 010 11605 A7.

I have the CG43 10E88 AL 010 11605 A8 but it shows the latest maps for 2019.

Aston Martin works shows a picture of CG43 10E898 AK 010 11605 A7 and states it shows maps for 2021 but the order part number is CG43 10E88 AL 010 11605 A8 same as mine but only show 2019 maps?.
