Would like to give Mike Benson at TST a big thank you for his response, I had a question concerning power for the new color monitor. I sent an e-mail to TST asking about power for the usb plug. I have an older RV that doesn’t have a USB port on the dash. I have a radio that has a USB port, but when I plug the USB cord into the radio, I lose the radio music. I received a phone call from Mike about an hour later, he explained, that I had a USB adapter in the kit that came with the monitor that would plug into the cigarette lighter. After rechecking the box, I found the USB plug in the kit that TST sent. Thanks again Mike for your help and the support TST provides.
