Installation Notes

Replacing the back cover on a Montana 700-series unit involves removing the battery, disconnecting it from the internal contacts, and separating the rear housing from the front unit. The original unit carries an IPX7 water rating and meets MIL-STD-810 environmental standards, so careful reassembly is needed to preserve that seal. One documented user report on Garmin's own forum describes recurring charging failures and random shutdowns on this series, which Garmin support attributed to a couple of different causes — including, in some cases, damage to the mount/cradle contacts rather than the device itself — so if your unit has charging issues in addition to physical case damage, it's worth confirming the cause isn't solely the mount before assuming the back cover replacement will fully resolve it. Professional installation is recommended if you're not comfortable with this type of repair. We do not provide detailed disassembly steps here, as incorrect handling can permanently damage the unit.

What's Included

• 1x Garmin Montana 700/700i/750i OEM-pull replacement back cover case (battery not included), 90-100% new condition

Buying Checklist

• Confirm your device is specifically the Montana 700, 700i, or 750i — not the 710i/760i or the older 600-series.
• Note this part does not include the battery.
• Note this is an OEM-pull part graded 90-100% new condition.
• If you're also experiencing charging failures or random shutdowns, consider whether the issue may be related to your mount/cradle contacts rather than the case itself.
• Confirm whether professional installation is recommended for your comfort level.

FAQ

Q: Does this include the battery?
A: No. This is the back cover case only — it does not include the battery.

Q: What condition is this part in?
A: It's an OEM-pull part (removed from a donor unit), graded 90-100% new condition.

Q: My device shuts down randomly or has charging problems — will a new back cover fix that?
A: Not necessarily on its own. One user on Garmin's official forum reported ongoing charging issues and random shutdowns on the Montana 700i/750i series, and Garmin support noted there are a couple of different known causes — one of which is specifically related to damage at the mount/cradle contacts during motorcycle use, not the device's back cover itself. If your case is also physically cracked or damaged, replacing it is still worthwhile, but a charging/shutdown issue may need to be diagnosed separately. (Source: forums.garmin.com)

Q: Is this compatible with the Montana 600 series?
A: No. The 600/610/650/680 series uses an older, different housing design — this back cover is designed for the 700-series chassis only.

Q: Does replacing the back cover affect water resistance?
A: It can, if the housing isn't reassembled correctly. Professional installation is recommended to preserve the IPX7 rating.
