Adding POIs and patching the OS are 2 different things mate.

Patching the OS = enabling the alert function to the OS.
Adding POIs = adding POIs to the OEM map disc.

The OS patch only works on a navboot file (mk4).

Use POISon.exe to add POIs to the OEM map disc, point E: page 1, post 1 of this thread.
