Got my JDM 4 weeks ago,
1. the Bose system works but thats about it, doesnt look that great and has a tape deck!!! my dealer said they would get it to work for the uk frequencys but couldnt so are going to fit me a new head unit that I will buy.
2. Mine came with Brembos
3. It is on the right and as lomot said you get used to it after a few journeys, my mum and dads car is the same
4. Mine got sorted when SVA'd
Hope this helps!!
