Got a neat gadget for Marilyn's car. I got her a Blue Ant bluetooth speaker phone. It does not wire into the car but has batteries and clips on the visor. It works great but you have to charge it every couple of weeks. So I bought a PowerFilm USB + AA solar charger. When you want to charge the handsfree device you lay the solar panel on the dash when you park and plug the Blue ant in. When you come home the battery is charged.
