These days, touching that cell phone while driving could land you behind bars. “What’re you in for?” “Sent an LOL going sixty.” “That’s hardcore, man.” Bluetooth earpieces are an option, but come on, you look ridiculous. Instead go for Nextar’s new solar-powered Bluetooth handsfree calling systems, the NXBT-001 or NXBT-002. Depending on the model, the tiny little speakers that bask in the sun offer between six and ten hours of talk time and do away with cables snaking around gearshifts. They hit the market this spring for $59.99 and $69.99. (www.nextar.com)   RYAN THOMAS
