Garmin Cable

[Pjturbo]

I got the 2720 from Costco and have it wired up on the bike. I plugged in the speaker wire but cannot get sound. If I pull the cable part way out of the garmin socket I get sound. This, to my mind, indicates that the garmin socket is mono as my plug is stereo. My autocom Pro AVI takes 3.5mm stereo plugs. Can one of you guys that has already invented this wheel direct me to the correct cable to hook these two together. Otherwise I may never find the hotel in Park City. Thanks.

Phil, I have a Garmin 2730 running into a Starcom. The 2730 is basically the same as the 2720 only with XM capability. The cable I am running is a stereo cable that I got from Jeff at SPORTBIKEFFECTS. You may just want to PM him and he can advise.....great guy, great service. The other person you may want to check with is GEEZER because he is running the 2720 on his bike but just into a set of headphones.

I seem to remember a thread talking about your same problem recently but I haven't been able to dig it up for you. Maybe one of our saavy searchers can pull up the link.

The plug in the Garmin power cable is Mono. The Isolated Stereo music cable is Product ID MUS-04. $45.00 bucks.

Yes, the cable that comes with the motorcycle mount has a mono female jack in it. I believe the 2730 has a stereo jack on the unit itself, but the 2720 has no audio output jack on the unit, just the speaker attached to the cigar lighter plug and the jack on the motorcycle cable.

Now that both the 2720 and 2730 have bben discontinued and are selling at clearance prices, the price of the 2730 is only slightly higher than the 2720, I would buy the 2730 rather than the 2720 if I were shopping today. That assumes they are both still available.

OK Here is what I did, Just got done doing it.

You need a Ground Loop Isolator (radio shack, bout 10 bucks)

Split the harness for the Garmin. Look at the one you use in your car and take the screws outta the little speaker to see what ones are the power. Run the power to, well power.

The other three wires are a crap shoot. What i did was get an RCA (red and white) to stereo adapter (radio shack again, cheap) and the other side of the RCA and cut it. (in other words I got RCA both male and female, the come in little Y configs. Radio shack again) I wired my other wires on to the cut RCA until I got sound (you will need an RCA to Stereo mini DIN to to get to the autocom)

So, Recap

Figure out where the power is by looking at the car one (wire colors) Wire your power. I got a little fuse block someone here reccomended

Crap shoot by guessing on what other two wires of the three remaining are audio by testing

Wire audio to a male RCA jack

Plug RCA jack into RCA that comes on the Ground loop isolator (DO NOT SKIP THE ISOLATOR YOU NEED THIS)

the other side of the isolator is RCA too. Get adapter to go to the autocom

You are golden

I can take piccies but not for a week or two. I will be on the road. BTW. I also wired my Radar detector audio in the same way on the other RCA leg not used above

I hope this helps

Total cost, bout 19-20 bucks

$20.00 and how long did it take you to do all that? :blink: Sounds like Jeff's cable might be the way to go.

 

[Cdogman]

Bouuuuwwwwwttt 20 Minutes. Did not have time to order cable, I am a master procrastinator, Now alas. I am leaving tomarrow for a long ride (11 days) and needed a certified for flight bike. So, I improvised

But there is no stereo output from the 2720. All you need if you want to use stereo headphones is an adapter plug from mono to stereo that you can get from Radio Shack for a couple bucks. Plug the adapter into the mono jack on the Garmin cable and then plug your stereo cable into the adapter. This is what I use to feed sound from my X50 radar detector to stereo speakers in my helmet. I assume it will also work to feed the mono signal into both channels of a stereo device, like the Autocom, but I haven't tried it.

I have the 2720 and the motorcycle mounting cable.

At the time I purchased my Autocom from Keith (918 446-2245 ) I also ordered a cable to go from the garmin cable to the Autocom. AutoCom Part# 191 (2.5mm Mono to 3.5mm stereo)

Keith at Tulsa Truck Center (918 446-2245 ) is the man to talk to about anything AutoCom

Couple of things...

Keith rocks, and you should order from him. He knows this stuff cold.

The Garmin harness is mono and you need a mono to stereo plug (call Keith).

If you've got the 2730, don't use the harness for audio, use the audio jack. The sound quality is much better from there.

If you've got the 2720, you have to use the harness, which sucks because of the sound quality issue above.

I've learned all this stuff through some painful testing of my setup. For the life of me, I don't know why Garmin outputs lower quality sound through the harness, if it is 'inside the unit' for the audio jack on the 2730.

Makes me regret not getting the bluetooth unit. I've heard people with Zumos plus the Scala Rider setup are extremely happy

I love tunes on my bike, and am somewhat unhappy with my upgrade to the 2730.

my 2+ cents...

Okay, it is time to get a GPS for the bike. I am looking between the 2730 and maybe the Zumo 450 if I can save the money for the Zumo. My question is that I have a Autocom M1. I already have my XM radio in the music input. Does the GPS go in the AUX input on the Autocom M1? I do not want to use my phone.

Any help would be great.
