Product Overview

This is a genuine OEM pull LCD touch screen display, removed from an original Garmin zūmo unit. It is a screen-only part — it does not include the outer frame or adhesive. It is intended for riders replacing a cracked, unresponsive, or otherwise damaged display on their zūmo 340LM, 350LM, 390LM, 395LM, or 396LMT-S unit.

Compatibility

Compatible:

• Garmin zūmo 340LM
• Garmin zūmo 350LM
• Garmin zūmo 390LM
• Garmin zūmo 395LM
• Garmin zūmo 396LMT-S

Important note on this grouping: publicly available compatibility data on this point is mixed. Garmin accessory listings note that mounting hardware for the 396LMT-S is not interchangeable with the 340LM/345LM/350LM/390LM/395LM series, which typically signals a different housing generation. However, this listing's screen-only compatibility across all five models is based on the seller's own hands-on verification of the connector and physical screen dimensions, not on a published Garmin specification. If cross-model screen compatibility matters for your repair, we recommend comparing your original screen's connector and outline against this part where possible before final installation.

Not confirmed:

• Garmin zūmo 345LM / 346LM (closely related model numbers, but not verified against this listing)
• Garmin zūmo 660 / 660LM / 665 / 665LM (larger 4.3" display, same size but a separate hardware generation — not confirmed interchangeable)
• Other zūmo series models not listed above

Common Replacement Scenarios

This part is typically needed when the original display shows:

• Cracked or shattered glass
• Unresponsive or partially unresponsive touchscreen
• Dead pixels, white screen, or display artifacts
• No image / black screen despite the unit powering on
• Touch input that fails after sand, dust, or moisture has worked its way between the housing and the touchscreen edge over prolonged outdoor use

Key Features

• Genuine OEM pull — sourced from an original Garmin zūmo unit, not aftermarket
• Combined LCD panel and touch digitizer layer
• Screen only — does not include outer frame/bezel
• Does not include adhesive; adhesive should be sourced separately for reassembly
• Connector and physical dimensions verified by the seller to match across all five listed models

Installation Notes

Replacing this component involves opening the device housing and disconnecting the internal flex cable that links the screen to the mainboard. A rubber gasket typically seals the edge between the housing and the touchscreen — prolonged outdoor use can allow sand or dust to work into this seal, so inspect and clean this area during reassembly. Since this screen does not include a frame or adhesive, reassembly requires reusing your original frame and sourcing adhesive separately. This repair involves delicate flex connectors and precise reassembly, so professional installation or prior repair experience is recommended.

What Is Included

• 1x Garmin zūmo LCD touch screen display (OEM pull)
• Frame/bezel: not included
• Adhesive: not included

Buying Checklist

• Confirm your exact model: zūmo 340LM, 350LM, 390LM, 395LM, or 396LMT-S
• Note that this listing is screen-only — reuse your original frame and source adhesive separately
• Compare the connector position and flex cable orientation with your original screen before ordering, especially if your model is the 396LMT-S given the mixed compatibility data on mounting hardware
• Inspect and clean the housing-to-touchscreen sealing gasket area during reassembly
• Confirm whether professional installation is required for your comfort level

FAQ

Q: Is the 396LMT-S really compatible with the older 340/350/390/395LM screens? I thought the mounts were different.
A: The mounting cradles for these models are indeed different — Garmin accessory documentation confirms the 396LMT-S mount is not interchangeable with the 340LM/345LM/350LM/390LM/395LM mount. However, the seller of this specific listing has verified the screen's connector and physical dimensions match across all five models, which is a separate question from mount compatibility. If you want extra assurance, compare your original screen's connector against this part before finalizing installation.

Q: My microSD card stopped being read, and the screen went blank/white — is that a screen problem?
A: Not necessarily. One zūmo 340LM/390LM owner found their screen went completely white after a card-reading failure, and traced the cause to a dislodged ribbon cable at the microSD card slot rather than the display itself — reseating that connection resolved it without needing a new screen.

Q: My touchscreen stopped responding after prolonged outdoor riding — could dust or sand be the cause?
A: Yes, this is a documented weak point on this device family. Sand and dust can accumulate between the housing and the touchscreen edge over prolonged outdoor use, causing the touch layer to malfunction, and over time this can also compromise the display's water seal.
