GPS in English?

I'd like to buy a car navigator/gps, but I'd prefer one that has an English language option if possible. (Not absolutely necessary, but I'd like to have it)

I live in Ehime, so driving is necessary and Google maps is kinda iffy. I'd prefer an actual navi, rather than an app, since it eats into my phones battery and all.

I honestly don't care about cost. I just want one with a good reputation and won't tell me to turn too early or too late and takes forever to recalculate a route... One that could be attached to the dashboard would be great.

Suggestions would be great! Thank you!

the price is about 50000 - 60000 yen

but, English maps does not cover all areas.
in Ehime, only Matuyama city area.

Yikes! That one above is expensive! I got mine at Costco for around 1man... works great, although we mostly use google maps these days.

Thanks for the responses!

Not sure if I can get to Costco, I don't think there's one on Shikoku..??

Unfortunately I'm not in Matsuyama either... But that link gives me a comparison at least~

My local book off (hard off??) has a bunch of second hand ones which seemed cheap and still in good condition, but not a whole lot of info on them... Might go in and check again when I get some time off and do a bit more research.

Thanks again!
