rover 100 radio code

[gavin1973]

Hi,

My mother has a rover 100 and the battery has been replaced.

We do not have the code for the radio & when we switch it on, it reads Err (can it be reset ??)

The radio type is a rover 660 type no: 22dc349/60B

the code on the side of the radio is RG 349FS 2016

your help would be much appreciated
