Hey guys, I'm new to the forum. I just wanted to congratulate you all on providing a great amount of info on this DIY.
I did the install on the larger solder points, as indicated above me. I also was able to do the spring & latch removal so that no dummy cassette is needed. The sound quality is absolutely perfect!
Thanks again!

And for those of you with the non-Bose headunit, I stumbled upon this.

I don't particularly recommend attempting what this guy did...seems like you'd need a hell of a lot of spare time.

The reason people even bother with this is the BOSE unit has speakers with impedance difference that require some additional work to use with AM receivers (IIRC half the ohms or something like that). IDK about the non-BOSE units. Just factor in new speakers to that new "radio" if you plan to yank the BOSE unit out.

The BOSE system is definitely a curse esp in the '03-'04 G, with six speakers (6x9's) and 2 high frequency door mounts, and double DIN form factor, XM tuner, replacing the entire system with something else is not inexpensive or easy. But it pretty much came in any car with the premium package, and the premium package pretty much came in every 6MT Sport, and so on...no really avoiding it. At least in the G is is one of the better sounding BOSE units I've had in other cars. Good enough I still have it, cassette player and all, LOL!
Good luck with your system, I remember mine in the Z was pretty toast after ~14 months, I rarely turned it on, def would have replaced it soon.

Not Working
Hi Guys,
Great forum here and great mod thanks very much to all that have contributed. I have done everything as per the instructions but I have a problem. I cannot use anything else like CD or radio and I cant adjust the volume or turn on/off. The only thing I did different was I wired in a 3.5mm headphone cable directly rather than an AUX cable. Could this make a difference? My headphone in works perfectly.
Cheers

I don't want to waste a whole day disassembling my dash/deck to find out it doesn't work on the G.
Thanks in advance!

is there any good way of doing something like this on a non-bose system? anything 3.5mm or ipod accessible
10. Caveats/warnings
This seems to work for me; I don’t use cassette at all so sacrificing it was an easy choice to make. It is pretty easy process (actually getting the dash off was harder) but breaking the PCB traces probably isn’t easily reversible, so be careful. I don’t know what will happen if you cut any of the other traces.
This was done on a 2003 350Z in Singapore – if your Bose headunit is substantially different from the pictures or doesn’t have the helpful labels on each trace or you don’t feel comfortable taking it apart you might want to think about some other route.
Hope that this helps some people.

Eric

The BOSE and the non-BOSE systems are very similar. Both should be easy to mod.
I am currently in the process of doing the mod myself.
Please cut your traces... Only Left and Right is sufficient. You can leave GND alone. I am looking at the schematic of the Clarion PN-2545E ( from a '03 G35 Bose w/ Navigation) but I assume the other variants should be VERY similar.. the PN-2545E is very very heavily based on the PN-2459EA. The PN2458Ex is also very very similar.
The AC coupling capacitor on the tape audio signal is placed after the point where you splice in your audio signal. You shouldn't only worry about the noise but also the fact that your device will also be driven by the audio signal processor in the car deck (this guy http://www.datasheetdir.com/HA12216F+Audio-Processor )
Essentially based on how your iPod or iPhone or w/e is designed it can be an issue or just add noise.
I guess an easier way to explain it is: You don't want the tape deck AND your iPod both trying to drive the speakers. They end up "fighting" kind of..
