How does one integrate "Here" maps into the VDO Dayton "Carin" format

Hi All

I am in South Africa and for the past 4 years we have had no longer map updates (discontinued) for the BMW "high" map format. These were used in the E46, E53, E39 etc BMW models.

Does anyone know how to integrate the current "Here" (BMW/MB/VW etc) maps into a the Carin format.

Looking forward to hear from the resident experts. :)

kind regards


George
