Garmin 378 Audio Out Noisy

[Dagny_Taggart]

I swear I searched and found naught the answer.

I have a Garmin 378 with GXM30 and the headphone audio going out to a J&M2003 unit. On a road trip, the XM audio sounds horrible. I plugged in a set of headphones directly to the 378 and it sounds horrible. Anybody have any words of advice?

Thanks in advance,

Dagny

LG - what kind of terrible, is terrible? Are you using the speakers in your helmet? Does it occur with different headsets?

I can use just basic "ipod" style ear buds on my 376 and the music via XM is just fine. I'd try just using a basic set with the 378 unplugged from the bike and the bike not running, then start adding variables back until you find the issue. Of course, if it happend at first, it would seem to be an issue with your 378 or XM puck.

I don't have my puck active right now, but I could easily. You are welcome to try it on your 378 some time.

Thanks Dave. I tried earbuds direct to the unit so it is the GARMIN units at fault. I did not try the unit on battery only (the power cord was still hooked up). When I get home, I'll unplug the 378 from the bike and try it on battery only.

I might cancel my XM for a different reason. I AM NOT buying another GPS so soon.

On the 478 you need to change the sound setting to "headphones" and not "line out".

Thanks Hoot I forgot about that. On the other hand, I can hear the XM radio but it sounds like an AM station at dusk. Wonder what Garmin charges for an audio repair?

It's not that old of a unit, is it? I'd try a call to Garmin's tech line.
