No they dont well mine doesnt , never seen it on the options list on the JDM brochure I have either??
Mine does, and it works.
I can see the elements around the foot of the windscreen.
I haven't got round to trying sat-nav yet, but the exsiting head unit has Jap sat-nav, and there is one of those GPS extra aerial things on the dashboard for it. I've tried unsuccessfully to get a UK CD for it. If I stick an after-market one in, I will hook it up to the aerial and see what happens.
