The State of Florida is required to send you a notice of suspension to the address that they have on file for you. If you have moved and not notified the DMV of your new address, their only obligation is to send the notice to the last known address you provided. The act of mailing the notice by the State is all the obligation they have and once they mail it you are considered on notice, whether you receive it or not. Since you were unaware, and this is (I assume) your first offense, you should ask the State Attorney at traffic court to amend the charge to driving on suspended "without notice" and then ask the court to withhold adjudication and impose the minimum court cost.
