Garmin Motorcycle hard wire install.

Found a great deal on a 2720 ($60) ordered the mounting kit ($30) and I am in the process of completing the install. As Info: I have a BC3 with a hardwired audio in located in the handlebar cover. I wanted to tap into that source for power....and audio..Yes its there.

My question: the Harness supplied with the MC kit allows to hard wire the gps. And has a 2.5mm female for the audio. The harness is a 4 wire harness. Red (power) Black (earth) and a white and brown. Using a continuity probe. I can't trace these back to the head or the harness. After 20 min on hold with garmin I gave up. Anyone know what the White and Brown wires are for?

Re: Garmin Motorcycle hard wire install.

I love the internet....Found the explanation on a GW site....

Quote:
If Garmin is using the same roll of wire for the Quest cables as they are for the 26xx series cables, the white and brown wire do nothing as supplied.

I tested for continuity from each contact on the connector and nothing seemed to be connected to those wires. I then used a knife to remove the molded plastic where the three sections of the cable (GPS, audio plug, power cable) join and found the audio coming from the GPS are on the brown and white wire. What Garmin did is cut those wires and attach the dumb audio plug there. It would have been so much easier if they just left it as a single cord and said here's your audio on the brown and white pair. Or they could have tied the audio jack to the brown and white wires so you would have a choice of where to connect. Since I didn't want to deal with the plug, I cut it off and re-connected the brown and white wires. Then repaired the cable with heat shrink tubing.

Re: Garmin Motorcycle hard wire install.

Garmin just modified the car power plug, the wires lead to a built in speaker in the power plug.

Brother Hoss.....did you hold 'em at gunpoint somewhere up in the Sierras? Way to go! You got a steal of a deal!

BTW, were you ever able to take the route through the base?

The ride is not until May. However, I have sent two emails to the Base PIO and have not received a response. When I get back in planning mode, I'll start calling the MP's (or what ever they are called there).

Funny thing about the Garmin. I ended up chopping the harness. The OEM has a 2.5mm Female that supports the audio. As posted above, instead of carrying the signal all the way down, the butchered the connection. I cut out the 2.5 and spliced the wires, soldered and heat shrinked it back together. Now the fun... The OEM GPS connection on the BC3 is a three wire. + / - / sp+. I have four wires coming from the Garmin. As I did not know which wire (Brown or white) was +, I started with the white. All worked great, audio from the GPS was piped to just the right helmet speaker, but there was a annoying hum. disconnected the white and when I did...POP! GPS fried! $60 down the drain....Now I'm bidding on another for "hopefully" the same price.... Live and learn...

As referenced, the motorcycle harness has these two wires cut, in order to allow for a 2.5 mm female connection for the audio. For the Car speaker, you are correct. I am thinking I could take it apart in order to confirm + & - for the BC3 connection...

Let me know if you need some support by fire with the Cdr.

"POP" .....I take it that is a bad sound! Something I don't want to try and do with an expensive Garmin....good luck my brother!

Re: Garmin Motorcycle hard wire install.

For the general assistance of the collective...The Brown wire is audio (+), white (-). Do not hook the white to the bike or........

The LT harness for the GPS or AAWD as the manual calls it. Orange (+), white (SP+), Blue (-).

That solves my problem also, but I am unable to locate the GPS connection on my 06 with V.O.I.C.E II. Only plug I found on the left-side of the Stingray was a 2 pin with Pink & White wires. (Another plug DIN I believe is for CB?)

Anyone know where the GPS connection is on a VOICE II system is?

Thanks

Can't help with the Voice, perhaps others will chime in. On the BC3 however it was UNDER the stingray. I do have a two wire (not sure on the colors) under the right HB cover, I believe this is for a Radar detector...

UPDATE: Well after a few days of servicing a friend LT, I got back to my problem. As it turns out the 2 PIN connection I mention above is the correct input. Now hear is the kicker, when I tried using the Pink wire all I got was very soft audio & very poor quality. So think I had nothing to loose, I tried just the White & you guessed it....NO I didn't low the 2610, the audio output is perfect, cuts out music etc to give directions.
What I need to do now is figure out how to input a computer 3.5 stereo output into the mono V.O.I.C.E. II plug I just found so I can have the voice directions from my UMPC?
Any ideas on this subject would be most appreciated....just had a spring snow storm in Edmonton so most probably no riding for a few days.

Re: Garmin Motorcycle hard wire install.

I found a hard wire connection through MountGuys.com. This link will take you to a complete list of power cables for the various systems on the market. After a quick check, it seems they have hard wire kits for almost every GPS made!

I ordered one for my Garmin Nuvi 370 ($27.35 total) and had it in four days (see picture with cable). It came with a pretty clear diagram (pictured below) to help me through the connection process.

I'm not sure if the diagram helps anyone out, but thought sharing the link to MountGuys was worth adding to this thread for others who may be thinking about doing this farkle add-on.

Ride Safe & BE SEEN!

Re: Garmin Motorcycle hard wire install.

Correct me if I am wrong, but the issue Phil is having is piping the voice from the GPS into the comsystem. The 26XX/27XX series GPS had an external speaker. The simple RED/Black on your harness is a 4 wire on these models.

A computer? 3.5 to the mono voice? Can you post a picture of what you are trying to accomplish. If it’s a simple Stereo to mono, I would think you’d have it buttoned up and happy by now…

Got that part working with my 2610, as I said I had to use the White wire only from the garmin harness to the White on the VOICE II harness.

Got it hooked up by using a 90 Degree 2.5 Stereo to 2.5 Mono, from that I used a 2.5 Mono plug & spliced a Black & White cable into the White & Pink of the VOICE II harness. Only trouble is now that I can only have the Garmin 2610 plugged in to hear directions. If the Samsung Q1U UMPC is plugged in I don't get directions from the 2610(If I'm using it in Nav Mode) I unplug the audio from the UMPC & I can hear directions from the 2610! But if I use Streets & Trip on the UMPC & use it in Nav Mode I hear direction from it!

Not a big issue as I wouldn't be using them both anyway, but does anyone have an idea as to what I might have to do ? Resistors?

Will Post Pic's when I have her buttoned up.
