Thread: Firmware for GTM 70 Digital Traffic Receiver up to version 2.30

I still have the 006B154600.gcd original file from my first ever backup of my device. Thinking about putting this back on to see if it forces a 'downgrade'

can you upload this backup file?
Thanks

Let you know how I get on. If it works will post it no problems

So added to the old file back on. Garmin express wants to update but the traffic receiver again. On power on and connection the unit did not 'update' to the old version. Gette if you want a copy of the file drop me a private message with your E-Mail; its only a 1Mb file so I will mail it over to you
