I upgraded from 7.903 to 8.412 in my GO300 V1.20.
I installed W&CE 2GB V845.2647 maps and found the postcodes didn't work, you enter them but they are not recognised.
I've just changed to CE V870.3319 maps and the problem is the same.
Is the issue the change from 7.903 to 8.412?
Any suggestions appreciated.
Thanks
Rod
