I'm just about to carry out this mod of fitting a mono jackplug socket. Does it make any difference how you connect the wires to the speaker?
i.e. which wire goes to which terminal on the speaker?

Yes, if you get them the wrong way round the unit will give you instructions in reverse - the best way to cure this is to drive backwards in the car, this normally counteracts the problem Laughing

just kidding! - no difference at all!
If you are concerned though normally a red, or a white, or a cable with a line (trace) on it is classed as 'live' - but this really bears no relevance to what you are doing, anyway will do! (said the actress to the bishop Wink )

Just done this, this afternoon 52pence for a mono female jack connector and it fits snug between the two locating lugs inside the case. I have set volume to 5 in the car but with earphone 1 or 2 is loud enough. Mind you with me loud pipes on my Harley I might need # 5 Laughing Out Loud.

Thanks for that - it helped me with mine Smile

PostPosted: Tue Jul 25, 2006 11:59 am    Post subject: Streetpilot i3 Vibration Reply with quote

I've been using my Streetpilot i3 on my bike connected to an Autocom unit from an audio jack socket wired to the i3's speaker terminals. One thing that I've noticed is a rattling noise (low level) coming through the earphones, especially on rough road surfaces. This disappears momentarily, as soon as a voice command is heard from the Garmin. I've come to the conclusion that this is a result of the speaker cone vibrating due to front suspension movement, which in turn generates the noise as an electrical signal. The Garmin is rigidly mounted on the front yoke so is subject to quite a lot of vibration.

Has anyone else noticed this on the Streetpilot i3? I have wondered whether it would be possible to surpress this low level signal by adding an electronic component across the speaker terminals. Any suggestions? My electronics knowledge is very basic.

I'm guessing that you've wired your headphone jack in parallel with the speaker, so that the speaker still works when headphones are connected.

Most headphone jack sockets have at least one changeover contact - the simplest solution is to rewire the socket such that the speaker is electrically disconnected when headphones are connected.

Thanks for the reply Ash. Yes you're right - I did just wire a mono jack socket in parallel with the speaker. How do I wire it up to isolate the speaker when the plug is used? Incidentally, the jack socket had 3 contacts on it - 2 of them isloated and one off the ground. I've only wired up to 2 of them.

I don't suppose anyone as a Idiots Diagram of how to connect so as to cut of the speaker when jack plug is plugged in
