There's a better link with more details.. It's battery powered and the charging input to the device is 5v. It comes with a car cig socket 12-5v adapter. It seems you need to stick a reflective layer on the inside of the windscreen so that you can see it properly (which puts me off a bit) Here's another link http://cgi.ebay.co.uk/GPS-Head-up-Display-HUD_W0QQitemZ260300812340QQcmdZVie wItemQQptZLH_DefaultDomain_3?hash=item260300812340&_trksid=p3286.c0.m14&_trk parms=72%3A1301%7C66%3A2%7C65%3A12%7C39%3A1%7C240%3A1318 Matthew > -----Original Message----- > From: [email protected] > [mailto:[EMAIL PROTECTED] On Behalf Of Jim Hearne > Sent: 26 November 2008 09:42 > To: [email protected] > Subject: [Quantum Owners] Re: Head up display > > But, as has already been mentioned, i can't see anything on > the Heads up GPS module that mentions it's supply > requirements and would agree that it almost certainly runs > from a 12volt lighter socket. > To make something obviously for a car that ran off 5 volts > would be silly. > > Jim > > > Tony Vincent wrote: > > On 25/11/2008 19:45:04, barnacle ([EMAIL PROTECTED]) wrote: > > > Arnie, I don't see where it states it requires 5v?
