Please let me know who the manufacturers of HDD NH3T-W56 Audio System are. This is the system fitted on my 2007 Toyota Raum and I intend to approach them for translation of the Japanese instructions therein. Thank you.
This website called Nengun shows the same model
NH3T-W56 (but the web site says "Toyota genuine". If that's true you should've asked Toyota for a help so I don't know if this web site is right).
You should contact Toyota to get support for OEM installed equipment in a Toyota.
