That is weird, I changed my ZIP code from the ZIP+4 to just the first 5 numbers and the page that tells me to select a county shows a pulldown menu of the two counties in my ZIP code. I gues it couldn't handle the +4 part. I assume it required the county to calculate sales tax... My tuner and remotes have been ordered.
