2820 question

[skellum]

Having read the review in another post I am seriously interested in replacing my Quest with the 2820 however, although the Bluetooth mobile phone option sounds a good idea as I would be able to connect my phone directly to the GPS and then access my directory/caller info and deal with any call from the touch screen - my audio connection would be via the audio/power lead connected to my helmet through an Autocom system - which leaves me with the question of how my voice gets back out - i.e. normally I would speak to the microphone system already in my helmet that leads back to the Autocom unit for bike to bike or directly connected mobile phone communication.

I have read that they supply a microphone with the GPS unit so I guess there must be a way of getting my voice back through the Autocom system to the GPS - hopefully can be solved - any ideas anyone?

Any help would be greatly appreciated

I'm thinking a bluetooth module thingy that plugs into the Autocom is what you need... In another thread someone mentions planning to use one with a Starcom.

I suspect that it may be possible to use signals on the main cable (the mono one that comes out the back of the mount), into the autocom in some way... build a custom cable... if only there was enough documentation... Garmin used to be really good at supplying pinouts for thier GPS's... haven't found the info for the radio cable on the Autocom yet...

Unfortunately the Autocom bluetooth attachment is huge (it's meant for a car!) and will not fit on a bike so I am looking for alternatives.
Garmin do mention an audio in (the microphone input) so I wonder if Autocom could fabricate a lead from the Autocom unit to this input? I do have a lead that connects the two way earpiece input on the mobile phone to the Autocom unit but if that is connected it would then disable the bluetooth connection from the phone to the GPS so I would be back where I started!

I use the item made by Motorola shown below

It has a speaker jack on the side so you just plug it into the Autocom

after you have done all the pairings its just a queestion of pressing the button on the side of the unit and it pairs automatically......or.........as I use it in the car as well permently pluged into the cigar lighter this means a soon as you turn the ignition on it wakes the unit up and pairs up automatically

I hope this all helps

ps the item shown is in silver I think they only now make them in black

Thanks Peter, probably the best bet would be to see if Autocom could figure out a way to get an audio output from the main Autocom box via a lead that I could plug in to the audio input of the 2820 - if that is not possible then could try the above however as my Autocom base unit is tucked away in the airbox it would be impossible to keep taking the Motorola unit out to recharge etc. There must be a way to do it!

I'm not sure if I fully understand your question - I think what you are saying is that you already have an intercom system on your moto that deals with voice in - voice out, and you want to know if it is possible to plumb a 2820 into that???

The SP 2820 has two mini phono jacks on the side of it, one for audio out and one for microphone input. I can't see why you would not be able to just feed your voice output into the microphone jack of the 2820, as long as there were no problems related to impedence, etc. It is specifically a microphone jack, not a 'line in' jack.

Hi Michael - thanks for your reply, at the moment I have a Quest that connects to my Autocom system via the cradle power/audio lead - this is hopefully being replaced with a 2820.
Although I will use this same lead on the 2820 to connect with my Autocom system and therefore will be able to hear calls direct to my helmet from my mobile that is connected by bluetooth to the 2820 - the only way I can get the output from my helmet (bike to bike) microphone would be to configure a lead from the Autocom system unit back to the audio in plug of the 2820. I am going to ask Autocom if this can be done.
Hope this make sense! if it could be done this would be a perfect system for me!

Hi Tony:

OK, great, have fun with it. Keep in mind that with any kind of electronics installation, it is usually quite simple and trouble-free to split up audio outputs between different devices, but it is considerably more difficult to try and split up microphone inputs. This is because we can always control the gain (volume) on outputs, but we rarely, if ever, have the ability to control microphone outputs. Plus, microphones seem to be far more sensitive to impedance changes, etc.

In other words - prepare yourself for the possibility that you might need to install a second microphone in your helmet to provide voice input to the GPSR.

Thanks for your help Michael - I will let you know how I get on once I have actually got the unit and worked my way through all the options.
