I have a TorHans aero bottle between the low stack bars and a sram attachment on the cross bar for the garmin. There is just enough room near the stem for the Garmin bracket. At a glance you wouldn't think so but it is a perfect fit. The aero bottle bracket needs to set forward a little more, zip ties keep the bracket in place. I've added some sticky velcro then velcro straps around the bars. Found the velcro straps at home depot, used for keeping electrical cables neat and tidy. My specialized set up is on a Trek so it may or may not work on a different model. The Garmin bracket did fit when we tried it on the shivs at my lbs.
