    I just got a good deal on a Garmin Nuvi 780. I installed it with the Panavise mount that bolts behind the climate controls. I think I would like to just hardwire it back to the fuse box. Has anyone tried this? I bought an extra power cord so I can cut the cigarette charger end off of it. Can I just use a 10amp add-a-fuse? Should I install this fuse in the first slot thats says "ignition" or is there a blank spot that is also tied into the ignition? Does anyone know the best routing for the power wire and where to bring the wiring up behind the GPS? I'll try to post a picture later of where it is installed, but it is basically just to the right of the climate control panel. I'm not a huge wiring/electronics guy, but I can pretty much figure anything out if I have some help from TW!

    I have not hired wired it yet....and I might not. I'm not sure that there will be any less visible wires if I do. I think it looks pretty good and it does not interfere with the shifter.

    If it's got the Nuvi mini USB plug for power- There is a hardwire converter for about 15 bucks on amazon.

    I didn't know enough about the power cable from the cigarette plug to want to tap that into the fuse box. I'm planning on splicing mine off the dash lighting wiring...

    What about the ones with free traffic? I think the "receiver" for the traffic is in the cable, so wouldn't you need to get another oem cable to splice into power?

    I have a Nuvi 265wt, and I think the cable is around $100. Am I right about needing that cable?

    Hmmm...Good question...I might have to call Garmin and toy with this a bit.

    I'd only be worried about eating that thing if the airbags deployed. Think that would be a problem?

    Mine does have that receiver built in. Thats why I was thinking of using an add a fuse and wiring it to an $10 cigarette lighter extension so that I can just plug the original power cord into that and hide that connection in the glove box. However, I might not even do that because the cable it came with really is pretty clean. The plug in portion is fairly sleek and it plugs into the GPS dock. I tucked the excess cable behind the portion of the plastic center consol by the passenger side.

    You can read my guide (listed in the sig) for ideas. Note that I later changed where I was getting power: I tapped into the 12V lead for the radio.
