GME TX4500 477MHz UHF Mobile CB Radio

DIN-Mount 477MHz UHF CB Radio DSP, 95 User-Programmable Receive Channels, Front-Facing Speaker, Advanced Signal Management

Product Overview

The GME TX4500 is the DIN-sized companion to the TX3500 a full-featured 477MHz UHF CB radio specifically designed for in-dash DIN slot installation. The DIN mounting kit is supplied, and the compact depth allows installation in confined dash spaces. A front-facing speaker is built into the front panel, combining clear audio delivery with a clean installation without an external speaker in most cases.

Advanced Signal Management (ASM) and Digital Signal Processing deliver superior received audio performance. Dynamic Volume Control adjusts output automatically for ambient noise. A large high-contrast wide-angle LCD display is clearly readable from any viewing angle; rotary squelch, channel, and volume controls provide direct, intuitive operation.

The TX4500 includes 95 user-programmable extra receive channels — the most in the GME UHF CB range for extended receive monitoring beyond the UHF CB band.

Important: No gimbal mount brackets are supplied. This radio is designed for DIN mounting only.

Features & Benefits

Frequently Asked Questions

Why does the TX4500 have a front-facing speaker when most mobile radios don't?

Most mobile UHF CB radios use a speaker microphone or external extension speaker for audio output — the radio body itself either has no speaker or one facing downward or rearward. The TX4500's front-facing speaker integrates audio output into the front panel, directing sound toward the operator for clear monitoring without a separately mounted speaker. This simplifies installation and is well-suited to DIN-slot installations where speaker placement options may be limited.

What does 95 user-programmable receive channels allow?

95 receive-only channels is the most extra-receive capacity in the GME UHF CB range. The user can program these channels to specific frequencies for receive-only monitoring of other services beyond the UHF CB band — the frequency range for these channels is not specified in the available data; confirm with GME. All programming is user-performed from the radio — no dealer or computer required.

Why is there no gimbal mount bracket and what does this mean for installation?

The TX4500 is purpose-designed for DIN slot installation only. A gimbal bracket mounts a radio to a surface (dash top, console, under-dash) at a user-adjustable angle. The TX4500 does not include or support this mounting method — it must be installed into a standard DIN slot in the dashboard or console. If surface or under-dash mounting is required, the TX3500 (non-DIN compact companion) is the appropriate alternative.

How does the TX4500 compare to the TX3500?

The TX3500 and TX4500 are companion products in the same radio series. The TX3500 is the compact version for slide-in cradle or surface mounting with a 3-rotary control panel. The TX4500 is the DIN-sized version with a front-facing speaker for in-dash installation. The TX4500 also provides 95 user-programmable receive channels compared to the TX3500's 19 dealer-programmed channels. Both provide equivalent communication performance across the UHF CB band.

Does the TX4500 require a separate speaker microphone?

The TX4500's front-facing speaker handles audio output directly. A microphone is still required for transmitting — either connected at the front or rear mic socket. Confirm with GME which speaker microphone models are compatible with the TX4500.
