As long as you don't have a CD or DVD multichanger I think you'll be ok.

 

Only thing i'd say is be cautious. A few things I discovered on my MK4 2004 sound system leads me to believe if you have one of the in-built amplifiers you may be in for a lot of pain.

I was trying to fit a parrot bluetooth phone kit, which effectively did the same as the kit you show does (patches into the existing wiring)

Hmmm.. I have a very, very good 8 speaker sound in my GV so I probably have the infinity system installed.
The volume is incredibly loud when I turn up the volume on my pretty standard 4 X 40W Kenwood player so my speakers are surely amplified (which is the case in the infinity system).
When I bought the car I just plugged in the Kenwood with regular ISO connectors and no problem at all.
I love the sound!

 

Sounds very likely vmaxxer, can you do me a favour, what exact model is yours, am trying to build up a set of references for models, years, versions, etc which may help for future.
Don't suppose you found where your amp was hiding did you?
(pm me if you'd prefer with details!)

 

I've never looked but always assumed its in the right rear quarter, there's a lot of info on the infiniti and wiring specs here if they are any use to you.

 

My Voyager you mean?
Its a 2002 Grand Voyager 2.5 CRD SE Manual gear, High Roof. By the dealer (re)build as a cargo van (2 seater).
I did not look for the amp(s) yet but I am surely building them out (with the speakers) when I ever get rid of this car and build it in its succesor
