is a hallmark of the professional analogue radio market, known for its ruggedness and reliability. To unlock its full potential, users rely on Customer Programming Software (CPS) to configure frequencies, signaling, and safety features like Lone Worker and Emergency Mode. Core Functions of GP340 Software
The primary purpose of the software is to manage the radio's 16 channels and customize its hardware buttons. Key capabilities include:
Frequency Management: Programming transmit and receive frequencies, which can be identical for simplex use or offset for repeaters.
Signaling Configuration: Setting up 5-tone selective signaling and Motorola’s proprietary Private Line™ (CTCSS/DCS) to reduce interference.
Safety Features: Activating the Lone Worker function, which triggers an emergency alert if the user is unresponsive, and the orange Emergency Button for instant help signals. motorola gp340 software
Audio Enhancements: Enabling X-Pand™ voice compression for clear audio in noisy environments and Whisper Mode for discreet communication.
Button Mapping: Assigning features like scan, power level (high/low), and talkaround to the radio's side and top programmable buttons. Essential Equipment for Programming To use the software, you need a specific hardware setup:
Programming Software: The standard version is CPS R06 (Professional Radio Series). Note that the software is often region-specific; for example, the GP340 typically requires the AZ (Asia) or MD (EMEA) region codes.
Programming Cable: A specialized cable connects the radio's accessory port to a PC. While USB versions exist, original serial port cables used with a Radio Interface Box (RIB) are often more stable on older systems.
PC Compatibility: The software was originally designed for older operating systems like Windows XP or Windows 7. While it can run on Windows 10/11, users often need to run the application as an Administrator or use compatibility mode to avoid file permission errors. Common Challenges: Codeplug Mismatches The Motorola GP340 Go to product viewer dialog
A frequent issue when using GP340 software is a "Codeplug Version Mismatch". This happens when trying to write a configuration file (codeplug) from an older radio into a newer one with different firmware. To fix this, you generally must "read" the radio first to get its current codeplug, make your edits, and then "write" back to the same unit. Where to Find Software Because the is a discontinued product, official support is limited.
Authorized Dealers: You can still purchase legitimate licenses and equipment through specialty retailers like Radiotronics UK.
Motorola Partner Hub: Businesses with a Motorola Solutions Customer Number (MCN) can sometimes access legacy downloads through the official Partner Hub.

The Motorola GP340 is arguably one of the most robust and widely used two-way radios in the history of professional mobile radio (PMR). Known affectionately among radio technicians as the "brick," it set the standard for durability in the late 1990s and 2000s. However, programming this handheld requires specific legacy software that can be difficult to navigate in a modern computing environment. The left-hand tree menu contains all configurable parameters
The term "Motorola GP340 software" typically refers to two distinct things:
For 99% of users, the Motorola GP340 CPS is the critical piece. The GP340 is part of the Professional Series (often referred to as the "Commercial Series" in the US). Therefore, it requires a specific version of the Professional Radio CPS.
Crucial Note: The GP340 uses different software than the GP320, GP360, or the newer DP series (DMR digital radios). Using the wrong CPS will result in a "Communication Error" or "Codeplug Too New" message.
The GP340 is a product of the early-to-mid 2000s. The software reflects that era, which presents modern challenges.
For the experienced programmer, the GP340 software offers nuance:
The GP340 is famous for its support of MDC1200 (Motorola Data Communication). Under the "Signaling" menu, you configure:
Real-world use: When a security guard keys up, the dispatcher sees "Unit 24" on their display before hearing "Lobby clear."
