You should be able to find them at Radio Shack but if you can not then here are some links. I am not saying to buy them from these suppliers I am just providing a link so you can see what you need.
6 “ Y Splitter:
http://www.amazon.com/Female-Stereo-Splitter-Cable-inches/dp/tech-data/B0016LDZ363.5mm Stereo Extension Cable with Right Angle Plug. You do not need a Right Angle plug it just looks cleaner if you are using the Auxiliary input on the front of the radio.
http://www.soundprofessionals.com/cgi-bin/gold/item/MS-SPSC-13.5mm Straight Stereo Extension Cable. If you do the radio modification to add an Auxiliary input port to the back of your radio you can use a straight cable. If you buy from this site make sure you select the 1.5 foot one.

A phone call comes in that I want to take. After assembling the rest of these forgotten HD parts, and adding your BOMM, must I switch to AUX in order to talk and hear on that cell phone conversation? Right? Will I still have CB and INTERCOM capability, simultaneous to the aforementioned? I really don't want the MP3 from the 660 since I have the IPOD module.
You must be in the Auxiliary input mode to hear anything from the GPS with the exception of a turn prompt if you have the NIM installed. If you are not on Auxiliary then you will not hear the phone ring so you will not know you have a phone call, unless you happen to look at the GPS and see it. You will still have intercom and a CB signal will interrupt the Auxiliary input mode so you will hear the CB.
Right now, with the INT OFF, CB OFF, AM/FM/CD/XM ON and speaker switch in the headphones only mode, I have noticed when the NAV instructions come through, if I blow into the mic, it is like the intercom is keyed up, the noise comes over with the NAV instructions and in the headphones. Is that the way it should work?
The NIM is not supposed to activate the helmet microphone.
These are problems with the NIM that have been reported to me:
The NIM intermittently activates when I am listening to MP3 songs. This is caused when the song or portion of the song closely resembles the trigger signal (turn prompt signal from the GPS) that the NIM is looking for. This can also happen when you are talking on the phone or if you have a 665 and you are listening to XM.
My microphone activates when a turn prompt comes though and I can not hear the turn prompt because of all the noise. Like I said the NIM is not supposed to do this.
I only hear some of the turn prompt. Sometime the NIM is slow to activate so you do not hear the entire turn prompt. You might hear “1 mile” instead of “turn left in 1 mile”
The Cellset works well but if you are a bit older like myself and your hearing is not the best then you want to stay away from it because it does not have the amplitude required for the hard of hearing. You also loose intercom and CB when the Cellset activates. What is nice about using the radio is that you have the amplifier capabilities and you can adjust the volume. Golden years my butt.
