will i retain the volume and seek function on my steering wheel after i install a double din on my 05 g35??? also will the bose system sound good as it does now or will the sound quality get worse once i put in an aftermarket double din in??

 

how did you keep the steering wheel function to change and lower music?

 

my friends the search here is a wonderful tool
what you need to get your steering wheel controls to work is an interface, PAC, Peripheral are 2 companies that make such devices. depending on your deck it will determine what you need.
and the bose system will sound better with the 7550 wiring harness. there's details about it but I'm gunna make you use the search button - I'm helping you, not hating
