I'm renting a car to drive around in Hokkaido. Any idea how to "key in" destination? Heard from friends that the GPS can search by phone number?
You can either enter by mapcode or tel number. Just select the appropriate option in the GPS screen. Abit difficult to describe here in text but your rental car agency staff will show u how to do it.
FYI, regardless of which brand/model of GPS headunit the agency install in their cars, only the voice guidance can be set to English. All other display on the LCD screen are still a mixture of Japs and simple english labels. It helps if u can read some Japs or at least Kanji else you will need to have lots of trial and error
And the map displayed will be labeled in Japs as well.
Be advised though GPS is not 100% fail proof. GPS signals can go wonky in big cities eg Sapporo where lots of tall buildings resides. You still need to have a map on hand and use your judgement in general.
