I use a HD Road Tech 660 with Harley's right side handle bar mount and with it turned down some I can see it pretty good in bright sun light (nothing is prefect in sun light), much better than when I used a Tom Tom 350. The other nice thing is I use a 16 GB Micro SD card in it and with the 660 on the right side handle bar I can easily reach it to access the maps or change songs (2600 songs) on the mp3 player. I've tried different coating on other GPS's and nothing seems to work very well.
Sorry, meant the left side for HD's handle bar mount, not the right side. Also with the HD mount it's much closer to you and easy to reach and see.
