electronics wiz required
I have a mio c710 sat nav with tmc traffic updates. I also have an autocom intercom on my car crash helmets.
The output is on the mio for an stereo earphone, but it is a shared 3.5mm 4 pole socket that is either used for 3 pole earphone or the antenna for
TMC.
I cannot use both at the same time!!!
The TMC plug is 4 pole so I am guessing that the tip of the male jack plug is the aerial and the earphones 3 pole, so I thought of getting a 4 pole
3.5mm splitter so that I can feed the headset and aerial together.
Problem is that they are not made!!!!!!
I ordered the 2 female 4 pole sockets and one male from maplins, to make a short splitter, but when I opened them up it looks like micro soldering
terminals. They are just too small for me to solder.
Is there anyone out there that can make me a splitter in exchange for some cash?

i know it sounds a bit invasive, but could you just pop the case off the mio, and solder onto the board a small lead with a 3 pole socket on the other
end, directly onto where the original 4 pole sockets connections are for the audio. would still have the use of the original 4 pole socket, and a
handy 3 pole for the audio? if u get me that is

how small are you talking with the soldering? i have fitted new micro switches into car key fobs a few times at work, which are pretty damn small
connections, if its not smaller than that i could prob make the adaptor up for you with the bits you have

The terminals are really small (they look like dots) and I am sure I will bugger them up with a standard soldering iron.
I need someone with a temp controlled iron, a magnifying glass and a steady hand!

If ketchup is busy I will happily act as stand in.
I have a Weller TCP iron (as used by NASA and almost everyone else) and the bride used to do military spec circuit boards.
Tell them about the bent treacle edges!

My wife does miniatures and dollhouses and some of the wiring in them is smaller than those terminals. We use one of
these and a 12v soldering iron and have had no problems with any of them yet. Tin the
connection and the end of the wire first then put them together and apply the
heat.these are handy as well, I mounted ours in an old desk lamp base
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

Not really, you just get it all spinning really quickly.
