Would Garmin be open to allowing the online community to vote on one feature per month? Doing so would quickly clear out the items that so many of us have been wanting for a long time.
Possibly Garmin could take the top 5 to 10 enhancements from the forum (based on comments) and allow each user to vote once. To keep everyone honest you could require a serial number from a Garmin device or use some other method of preventing multiple votes from one user.
