Hardwiring a GPS for a car?

Im considering buying a gps for my car( Probably a Nextar X3-03), but I am wondering what is on the market, if possible for this model, in the way of a hardwiring kit directly to the fusebox? I am comfortable wiring the kit for myself, I’ve already done it with a radar detector, but if anyone has info, please share.
I dont want to have to cut up the wires – basically I need a cord with an AC power cord for the GPS and the other end of the cord to be a direct wire, not a wall outlet or a cigarette lighter plug.

I put an aux outlet under my dash. You can get them at wallmart autozone etc. it’s easier than cutting the gps wires.
