My '11 35i has not been updated, and behaves similarly with that address. I put in:
and when I right click with iDrive I get a list of villages/neighborhhods (Harwood heights, Jefferson Park, etc., followed by a list of Zip Codes. Each listed village/neighborhood and zip code seems to have a section of N Milwaukee in it. Trying each of them, it's only when I get down to 60647 that I can enter 1800 as a street number. I haven't run into this before. It's got nothing to do with the update, because I don't have it. The problem is likely a GPS data or GPS software logic flaw. I expected, as you apparently did, that the GPS would give me N. Milwaukee Ave, and then let me put in a street number.
I don't know Chicago at all. Is N. Milwaukee unusually long or something?
