GPS Navigation.. Please Help!!

I recently purchased a GPS system to install in my 2003 tiburon. I am having trouble finding the VSS wire and the reverse wire that it requires. These two are very important considering it lets the satellite know where you are. Has anyone installed one in their tiburon? and where are these wires located? I was told under the front dash fuse box, but i have no clue where to go from there. Thanks..

dont know where the wires are but..... return the navigation system then with the money by a road atlas of the country

take it to a shop.....

take it to a shop.....

yep, if you dont know what your doing or the instructions arnt clear enough, your better off having some1 else at a shop instaling it rather than you mess up your car.
