Anybody here bought/installed/made themeselves a hardwired, built in cellphone charger that is concealed insde the dash? I hate having the regular charger dangling out of the cigarette lighter. I was thinking hiding the 12v to 3v converter underneath the dash and then running the end that plugs into the phone into an accessable but hidden location. Maybe the ashtray or the overhead console sunglasses holder. Any ideas?
