gps coordenates

Does anybody knows how to change the gps navigation coordenates of a Tacoma 2017? it comes 18.??? and I need five digits after the 18. ex 18.12345. Any help will be thanked...

 

Subbed. Also wonder if there is a map update for much more detail on forest service roads, etc. The stock one has nothing.

 

You need to convert from that to degrees minutes and seconds. Google it. It'll be close but Taco doesn't get as detailed as you want. What I do when the numbers are off a little is, say the last digits are .27 just round down. If over 50 round up. You'll see the location on the screen and can nudge it to be best spot manually. It's not that bad really.

See what I mean about the result? That 44.33" isn't gonna go into Taco. So for this one round down to 44. It'll make sense.

 

Thanks everybody...
