However, the address in question (both OPs and yours) only have one possible combination, that's in MO, based on a google search of just the building number and street name.
That said, I know the BMW Nav sometimes has issues with same street names in neighboring counties. For example, "El Camino Real" here in SF Bay area spans 3 counties. The user can incorrectly enter the city, but the Nav would hint there is an "El Camino Real" in SF, San Mateo and Santa Clara counties.
Further, the Nav also has issues with exact naming conventions. As noted, we may call a street "North Broadway", but the formal address should be "Broadway North" and follows the formal post office address. This is a common issue when I entered my old address in Arlington, VA which was technically "Nineth Street North", but most people call it "N. 9th Street". Google accomodates for this naming convention quirk, but when I get items shipped, the address correction always shows "Nineth Street North", which is what the BMW Nav also prefers.
The only issues I've had with my 2012 CIC Nav is with warehouse/business or condo block addresses, where 10 building numbers can be associated with the same block.
