GME’s MC634B LCD Controller Microphone suits TX3350 and TX3550S radios and shifts the radio brains into the handset, handy when the main unit lives under a seat or deep in the dash at around 0.5 m away. The SoundPath speaker fires audio from the mic body straight at the driver across a 1.5 m wide cab, so you can still catch every call over tyre and wind noise on long dirt stretches.

The mic shell is solid plastic with a compact head around 65 mm wide, so it mounts cleanly on most flat dash or console spots without crowding other gear. A coiled lead that reaches roughly 1 m lets you lean out the door or reach across the cab without stressing the plug. Button layout matches the TX3350 and TX3550S controls, making this a smart buy if you want full UHF control in hand without moving the main unit.

Q: Does this microphone replace the original handpiece?

Yes, this microphone replaces the original handpiece on compatible radios. The MC634B plugs into the same microphone port as the factory mic. Once connected, the LCD and controls on the mic take over day-to-day operation. Keep the old handpiece as a backup in your kit. Swap back by simply unplugging and reconnecting.

Q: Can I use this with any GME UHF radio?

No, this microphone is only suited to TX3350 and TX3550S models. The wiring and control layout are matched to these two radios. Using it with other models can stop functions working properly or may not connect at all. Check the model label on your radio body before ordering. If it does not read TX3350 or TX3550S, this mic is not the right choice.

Q: Is the speaker inside the microphone or the radio body?

The SoundPath speaker for this setup is inside the microphone body. Audio comes out of the mic housing instead of the main radio chassis. This helps in cabins where the base unit sits under a seat or behind trim. Mount the mic clip where the sound can travel freely. Avoid covering the rear vents so the speaker can breathe.

Q: Do I need extra brackets or hardware to mount it?

The microphone can hang on a standard mic clip. Most UHF installs already have a clip or hook on the dash or console. The MC634B head is similar in size to many standard mics, so it fits usual mounting spots. You can move the clip to suit your reach in the driver seat. Use existing screw points where possible to keep things tidy.
