I bought a Subaru Forester 2009 from Japan It has a Kenwood HDV790 navigationsystem and it is in Japanese. Where can I get an English manual for it?

I would go to Kenwoods website and look for a link to their support center and see if they have online manuals or at least ordering capabilities. Most of the big electronics companies have this option, I did it for my JVC stereo. I lost my manual over time, had to replace the battery in my car and had to reset most of my settings on my stereo and I was able to get one from JVC. Just make sure you write down the number on the front of your unit on some paper so you can research it by model on there site. I hope this info helps!

You absolutely cannot select any other language on Japanese domestic SONY models. The professional line up of camcorders come with an English selection in the menu, but not the consumer models.
Suggestions by well intentioned but ill-informed people to follow the menu in the English user guide, will not get you anywhere. The Japanese models do not include this item in the menu. Plain and simple.
Visitors to Japan should be careful when purchasing items here as they more often than not only include Japanese manuals. SONY and Panasonic also only include English menus in their cameras. Canon and Nikon do have an English selection, but this should be confirmed at the point of purchase not after returning to your country!! Furthermore, warranties are usually only valid for Japan.

Sony cameras in Japan only have Japanese now it seems. To get English you need to buy an international model for an extra price.

How do reset the japanese languange to english in toyota vanguard nhzt-w58

I bought a camera in Japan (Sony Cybershot DSC-WX1) and now it seems that i can't change the language from japanese to english. If i select (can't read it but with the help of the english digital guide i think i have the right menu)change language, there seems to be only one language available. -japanese- How do I solve this?

I am afraid,that Panasonic in Japan provides only Japanese language for the Japanese market. English or any other language is only included for the models aimed for export

most of the nv-gs50 cannot support multi-language (i.e. the ones manu/bought in japan).

you may be able to find a firmware update, but i would not recommend it---i.e. you are stuck with japanese
