I wired my TomTom XXL 540 directly to my battery and because the OEM power cord reduces the voltage from 12V to 5V (which obviously I was unaware of at the time) I fried the GPS. Is there anyway to repair the GPS and get it working? Thanks!

You need to remove top and check for 12v and 5v,( put multimeter leads on wires one at a time) going into display panel from main board. If you see 12v and 5v than display board is very bad.If no voltage at all then main b. is bad or the noise filter( connects to power cord) fuse is bad.
If you are referring to Latitude and Longitude , yes. You can use those co-ordinates to navigate to a destination. This especially works fine in countries where the Avenue and street information is not available. Google maps can give you the latitude and longitude coordinates. You can fed those into the GPS and navigate. Please note, you will need the maps of the region involved.

Tap on: Latitude longitude
Enter latitude and longitude using keyboard, Latitude first and longitude next. Be careful while you do this and do not forget to enter the directions North, West etc.
I've wired my tom tom for use on a motor bike. you CANT run 12v straight into the tomtom, you can see on the cig lighter plug it has a 5v output. So I bought cheap lighter socket, it looks like plastic tube with the cable running out of the back. So the wires run from the battery (via an in line fuse) to the cig adaptors, these are hidden in my side luggage bag to keep dry and up to the tomtom. job done
