come on pipe get those pics posted

Hello Allroad how you like the sun in Marbella, better than homes yes?

Look like the splitter unit outside, will give Garmin a ring in the morning to see if it's been reworked internally.

Thanks

Apparently the original splitter will not work with the Zumo, it allows you to hear the MP3 player and phone but will not accept speech.

Hi Guys
I have the pre 2006 Active 7 Smart Autocom. I will need the item 999 (now 1300) from Autocom for my Zumo 550.

Been following info here and here
h**p://razorbiker.com/zumo/viewtopic.php?t=491

Has anyone fully tested this Audio lead and how it reacts with Autocom and added accessories?

Does Bike-to-bike mute when Zumo MP3 player in use as per Brian at Razorbiker. This would effectively rule out Bike-to Bike comms because at the mo Active 7 cuts out all other source inputs upon phone ringing which is connected to phone input on Active 7, i.e. music and Bike-to-Bike.
Is the phone connection by wire or bluetooth and does the phone function OK
Is there a reduction in audio volume by using the phone input for the Zumo.

Going to contact Autocom this week but interested in users experiences.

Just for the record, neither the Autocom nor the Starcom leads for the Zumo deliver proper stereo mp3, they have been wired to deliver mono audio into the phone-in socket .

The only way to make it work properly is to wire the 3.5 stereo out jack on the Zumo to the stereo music in socket on the Autocom (via a ground loop isolator), then wire the mic socket on the Zumo to the phone in socket on the Autocom (goes to the middle pole and earth). That way you get phone and true stereo music at full quality.

I'll try and do a wiring diagram so you can see what I mean.

Well spotted, if you wire it the way I describe above, it does work properly with bike to bike because the audio from the Zumo goes in to the music-in port on the Autocom which get's muted to 50% when you receive a audio signal from the PMR radio. The Autocom won't mute the music when a call comes in because the audio from the Zumo isn't going into the phone-in socket, but that doesn't matter because the Zumo pauses the music when a call comes in anyway, which is a much better solution IMHO.

Thanks for the info. Much appreciated.
I'll talk to Autocom but looks like I'll be wiring as you described (seems same setup as Brian on Razorbike who used 2 x #1314 leads from Autocom which are isolated to reduce interference)

The use of phone is not a priority for me but fully functional music, in stereo, Bike-to-Bike and the satnav prompts is.

By the way Wiz, "isolated leads from Autocom" is this the same as "ground loop isolater" you mentioned. Drawing would be great. Autocom leads are expensive.

No probs. Yes, the "ground loop isolator" (GLI) is a generic name for the thing Autocom sells for about £25 . Cheapest place I've found to get one is here:, you can also get them from Maplin here: . If you already have the Autocom one, you can use that as well no probs.

The wiring is simple really. I know why Autocom got it wrong and I'll try to explain below, but let me make the wiring clear first.

Music: stereo socket on the Zumo into the GLI then from the GLI into the music in socket on the Autocom.

Phone: OK, the phone socket on the Autocom has 3 poles: Speaker, Mic and Ground:

round tip = microphone
ring = speaker
sleeve = ground

The Zumo "Mic" socket only has a two polls on it (mono). It doesn't need the third poll because it only carries the mic signal, not the audio one. The Music-out socket from the Zumo carries both the Stereo music signal AND the mono audio signal from the phone. So, on the mic side, you'll have two wires coming from the mono mic jack socket on the Zumo, which need to be soldered to the mic and ground polls of a 3 poll (Stereo) jack that will go in to the Autocom. The mic lead does not need to go through a GLI because you are not carrying any audio in that cable. The middle ring of the jack plug is not used, that would usually carry the mono phone speaker signal.

OK, what both Autocom and Starcom have done is to connect the left and right speaker signal wires from the stereo socket together making one combined signal and have put that into the mono phone-in socket on the Autocom (or Starcom). This is frankly a crap arrangement, because not only do you get mono sound, but the phone circuitry in the Autocom is not designed to carry a quality music signal - only basic speech. It also means (as discussed above) that the music will not mute to 50% when you receive speach via your PMR radio.

I can only think that Autocom wired their lead this way because they mistakenly thought that the Autocom would get confused and keep halving the volume if you feed speech into the music socket, but it won't, because thee is no audio going into the phone socket that will trigger the 50% mute function. The music will cut out completely when you get a call because the Zumo will automatically pause it.

Ok if you have got this far without nodding off and still have any questions feel free to PM me or email me at wiz (at) bikersoracle.com

I do know a couple of the tech guys at Autocom so I'll speak to them about it over the next couple of days and see if they'll amend their lead.
