My GPS (SP2610) is wired into my Autocom unit via Part 57, the black/red isolator box.

According to the instructions, I need to plug the GPS into socket A, and the plug from Part 57 into the Aux socket on the Autocom (Pro Rider).

But I can not hear the GPS at all.

If I plug the GPS lead into Socket B, I can clearly hear Gertie Garmin, but also a rev-dependent electrical interference noise.

Thinking that I had a dodgy Part 57, I dropped into Bahnstormer last week with the intention of buying a new unit. Simon in Parts gave me a unit to 'try before I buy'.

And guess what? Exactly the same problem. Nothing comes through from Socket A, but I can hear clearly from Socket B, albeit with the aforementioned interference.

Has anyone got any bright ideas about what might be happening?

At the last resort, I will ride up to Autocom to let them look over the system.

Does the interference follow your RPM exactly, ie when you blip the throttle, or is it a more gradual build up that dies away completely below, say, 2000rpm - and does it perhaps sound like "chip fat frying"?

One more question. Have you, or can you, feed the audio direct to your helmet from the GPS rather than via the Autocom; and if so is the interference still present?
 
what cable are you running from the Part 57 to the GPS mate as this can make a difference? Also it could be the usual Garmin bike power and audio lead problem we the two leads need to be cut and shut together.

The interference noises are exactly rev dependent. It's loud enough to be a pain and stop me using the GPS sound.

Not sure how I can feed the signal direct to my earplug monitors without buying an adapter plug thingy! Both my Green Leopard minors and the lead from the GPS end in 3.5mm plugs. I might try to find a female-female connector in Maplins today, if I can get to one.

The lead to the Autocom is hard-wired at the GPS end. That is to say, I have removed the little socket on the GPS lead, and removed the plug from the Autocom lead, and following the instructions I got from this site, I've welded both leads together!

The cable I'm using is the Autocom one I bought from SPC.

And, as I mentioned in the first post, there is obviously a sounds signal arriving at Part 57, so the cable joint is 100%.

Question, then, is what's the difference between the A and B sockets? And can I open the box and make some alteration to the B socket so that I can hear what's going on? I have no need of a phone connection. I only used this Part 57 as SPC told me it would avoid electrical interference because my Autocom and GPS are both bike powered ....
 
MMMMMM Im unsure to what is going on here mate, The way the Part 1282's are wired up Socket A is isolated and only allows signal in from a GPS or Radar detector. The Socket B is not isolated and allows for signal in and back for phone use so its not really possible to get the internals reworked.

All I can say mate is post the part back to me so I can get it checked over for you.....or if you fancy a ride over grab yourself an appointment

Your interference problem appears very similar to mine although my GPS is not bike powered. My dealer, after consulting head office, agrees with me that it is not an Autocom issue but electro magnetic interference from the alternater or ignition

I have tried a ferrite bead decoupler on the audio cable and in an attempt to find out what part of the audio circuit is picking up the EMI. Running the GPS from internal batteries at varying distances from the bike may provide a clue

Will be interested to hear what develops in your case
 
Can ultimate ear be connected to Bluetooth devices?

I'd like to connect my ultimate ear in monitors to a Zumo 550 but would like to stay "unplugged" from the bike so I can jump off without disconnecting any wires. Is this possible??

Cheers,

Andy

SP2610 doesn't have any internal batteries, so it has to be wired to the bike.

Intaride have at last launched their proprietary headset wireless system called Intaride Liberty. It is intercom agnostic in as much as it needs one but doesnt care whose make it is. From what Ive read it isnt a Bluetooth solution, but they do claim good quality audio. It has a free hanging mic and speaker jack - you should be able to wire in another socket or similar to fit your earplugs or monitors.

Oh, it is a tad expensive mind :eek:

Dont know anyone whose got one yet, but quite a few have been interested in this development.

Have fun,

Mike

I tried the very first working prototype of this and was very impressed with the design and quality. At the time there were some manufacturing problems with getting hold of one of the components but I lost touch with it. It's certainly giving the guys at IntaRide a ring to find out where it's at.
