BAI Bank Administration Institute statement file import

I need help to find out if there is already an interface available: we need to import bank statement information to NAV bank reconciliation from a file format called BAI2 or BAI2a as it is called at the Bank of America (BAI2a is containing century information vs. BAI2). Bank of America is the bank we will get the file from.

The NAV customer version I am working with is technically 5.00 SP1, object version UK 4.00 SP2. A German banking application has been renumbered, imported and adapted to create Bank of America payment files.

Anyone knows of a bank interface for BAI2? Maybe the North American version?
