The unit comes manufactured with double-sided tape, and a big solder join in the center under the antenna. Despite that, others and I experienced loss of satellite reception due to that solder joint failing due to long term exposure to vibration. The OEM tape and solder are not adequate. Garmin offers Montana as a handheld trail unit, specifically does not offer it among their motorcycle-suitable devices. Does "better tape" exist? You'd have to re-solder the antenna to get it off, replace the tape, solder it back on... I will always carry the external antenna as a backup. This is all a lot of hassle for a GPS unit...
