Should I swap out the head unit once I get my 370z?

Right now I have a 2004 civic with an after market navigation made by pioneer. I noticed that the touring 370z doesn't allow you to swap out the bose head unit but the non-touring does. I'll be getting a 2010 370z 7AT with sport package by the end of this year. I like in-dash navigations alot more than portable ones because of the accuracy of the signal, screen size, and i don't have to hide it when parking somewhere. If I get an after market navi for the 370z it'll cost about $700 installs at my mechanic. I'm a little worried tho that he'll mess something up, is it possible he messes up when he does it and messes up the paddle shifters or mess up the AC, fan speed knob. I also feel a little bad throwing out the stock radio being that it's new and all. Should i just get a portable one? What you guys think? thanks for any suggestions
