I just purchased a new 76CX and the cursor button which should have a tactical feel at all four positions squeaks at the 6:00 position and is missing the tactical feel at that position. Seems like a defect to me that I'm concerned about causing a bigger failure later. Pushing the button at the 6:00 position doesn't always cause a movement on the screen. It has to be pushed harder in that position. ALSO, This unit came with a 1G San Disc Micro SD card inserted in the slot. I thought these things came with a 128MB card. Was there a change in what Garmin includes with this unit? Thanks.
