Hi got this head unit in my van, good sound but as usual in Japanese,  can I convert to English,  any hacks, tips or tricks?  

  Thanks in advance 

Mine is a different one but Google Translate app is very helpful in setting up the Bluetooth pairing. 
There are plenty of options to mess with, but you do need the translate app. 
 

 

It’s a good system when you get used to it. 
Only problem is the radio frequency range only includes Radio 2. 
You can pair your phone and listen to the Radio via the internet and hear it through the cars speakers though. 
 

Yes it's good, I do use Google translate I've put a few cds onto either a hard drive or similar inside the system... Great sound
