IGO problem in Sacramento, CA

I'm not sure why but my IGO GPS won't acknowledge S street in Sacramento, CA. When I drove by S street and put in a random location it thought S street was South street.

Does it work with the other single letter street names in Sacramento?, such as P Street and X Street, I'm guessing the software has a minimum character count for a street name search
