Accessory Power FlexSmart Car Mount System for SmartPhones - Cutting Edge FM Transmitter and Charger with DC Surge Protection and Stabilized Flex-Neck
Too top heavy, twists around and ends up upside-down.  I had real difficulty finding an empty station to use.  I was not impressed with the sound and its not my speakers, they are new. If it has a soft cord to plug into the lighter then its probably ok but mine is rigid to stick up where you can get to it and won't stay.
