So I took my Z to Tweeter to have the head unit replaced. Come to find out that for me to get a new head unit in, I would need to replace everything, because the computer in the car is dependent on this. Has anyone else run into this issue? The tech stated that there should be an adapter available within the coming months which would alliviate this problem. Has anyone encountered a fix for this yet?

 

No such thing. I installed the Kenwood 915 into the Z leaving the stock speakers and amp. No problem whatsoever.All you need is the wire harness and dash kit. In fact, changing the headunit is a good temporary fix from the crappy oem Bose headunit. If you have nav, maybe someone else can chime in and help.

Wireharness part #:Metra 70-7550

 

The problem only resides with the 2004.5 models I think. I did by the kit and harness it was a no go.

 

he's feeding you a line. do you have navigation? if so you will lose the voice by changing out the head unit but nothing else is an issue. if they were competant they can actually re-hook up the nav voice.

my advice - go somewhere else (or better - do it yourself - it's incredibly easy)

 

thanks for the info...looks like I'll not be doing business with them in the future.

 

I've yet to hear a good experience with Tweeter, I mean I'm sure there are people out there who are happy with them, but everyone I know complains about price and service.

 

Yeah, I thought everything had to be changed as well, but it doesnt. Also, make sure the antenna is plugged into the headunit when you try turning it on the first time. When I installed my headunit, I didn't plug in the antenna and tried turning it on...it wouldnt turn on. I plugged in the antenna and the damn headunit turned on. I have the sony 7700 so it maybe just for that.

 

Do you have a bose system?

I think i know a few ppl who works at that tweeter location. If you want I can find out for sure, if you are still interested in going back there.
