Looking at the specs for the 370, I would guess not. The 370 is not listed as motorcycle friendly on Garmins site. I have the Zumo and you can do Bluetooth for the voice prompts. The problem with the bluetooth on the Zumo is it doesn't support stereo, so the built mp3 player would be mono.....no good.
I ran a hard line under the tank and plug in the helmet speakers when doing a road trip....you get voice prompts and stereo mp3's......
