Garmin 2720 Installed
I installed a Garmin 2720 on my K1200LT today replacing my older StreetPilot III. Initially, I was getting a buzzing sound whenever I turned the 2720 on, even if the audio connector was unplugged. I had hooked the 2720 power cable up to the same leads that the SP III had used. These were on a harness coming out of the Voice II (or is it III?) providing +ve, ground, and audio. The SP III had no buzzing sound.
So I rewired the 2720 to get power directly from the battery and the buzz went away immediately.
The audio is passable but not as good as with the SP III. As with the SP III, I can avoid start of speech clipping by turning on the "announcement" option. But I get a fair bit of clipping at the end of a speech string. For example, it will usually miss the "street" or "road" at the end of an address. There is also a high level of background noise whenever it speaks. I tried it both with and without an audio ground and it doesn't seem to make a difference.
If anyone has good quality voice with a 2720, please let me know. The audio is great when used in a car of course.
