Hi,
I have the same head unit. It was a total nightmare for so called professional installers at RAM. I beleive there's 1 in Hull, but I wouldn't recommend them. It's OK now, but they had my Z, 4 times to sort it.
1st time it came back with just the head unit change and I had no Sat-Nav sound.(3 days it took-em)
2nd time, no sat-nav or front speaker sound (All bose stuff removed). (Another 3 days)
3rd time, got all the sound back, but they had to take a transducer out of the Bose head unit to get the sat-nav to talk again. They delivered the car back (only 3 months old at the time, which made it worse) Didn't set up the system and to top it off they'd dinked the NS front wheel which they denied. (TOTALLY CRAP SERVICE).
So... to the point. The Bose kit is garbage, bin the lot. Get someone in who knows his stuff and Dyna-mat everything.
My Alpine R310 unit is spot on. 2 Alpine amps (1 for the sub and 1 fort the speakers). Speakers are Hertz Hi-Energy.
You might have seen these pics before... If so sorry...
Hope this helps.....
