Convert GM660 to GM340

Postby bradlington » Sun Sep 20, 2015 1:13 am

It has been a good few years since I last hacked the GM660 to a GM340 .

At the time I battled and tried all avenues and managed to convert one unit .

Shortly after that I had to put the project aside and never made accurate notes,

Anyone have a step by step procedure for this reflashing from a GM660 to GM360 .

Thanks in advance.

Hello,

I'm looking for the same thing. i have 2 x GM660 and want to use the GM360 codeplug for it.
I know that i can use it in a conventional way also but I need to change some stuff that i can only find on a GM360 radio like pinout options on the back connector.

The old CPS for 660 has not many features like channelname on the display.
I have all needed software, cables RIB,... All I need to know is a step by step procedure to convert the radio's.

Greetings

Tom
