This article also applies to GP320, GP330, GP360, GP380 radios. But this article does not apply to GP640 and GP680 as, whilst they share the same accessory/programming socket, GP6xx radios require different software.

What Do I Need?

We recommend that you go for an after-market USB cable which will make your life a little easier. We’ll concentrate on that option here. But for convenience, we have put details of the genuine programming kit at the end of this article. Note: The GP340 and GP344 have different accessory and programming sockets but they use the same software.

Operating System Compatibility

We have tried and tested ENLN4115 GP Professional Series CPS on both Windows XP and Windows 7. We’re unsure if it will work on Windows 8 and Windows 10. If you try it and find it does work, please email us sales@radiotronics.co.uk and let us know.

How To Program A GP340

Upgrade Motorola GP340 Firmware

If you’d like to upgrade the firmware in your Motorola GP340, you’ll also need a HLN9742D flash adapter which only works with the genuine RIB box (and you’ll need everything in the list above). We’ve tried firmware updates using an aftermarket RIB box, and whilst the aftermarket RB box works for programming – it did not work for firmware updates.
