Want radio with Scan mode

My pioneer model broke, so I want to buy a new car radio, possibly with HD radio. I'm looking for a radio that actually has a scan button where you can actually push it one time and it automatically goes from station to station, stopping a few seconds on each station across the whole band. The radio that broke as well as the radios in the stores seem to only have the "seek" button where you have to constantly push it to go through all the stations.
