As you talk about RDS are you in Europe? I have had this issue since day 1 with my car. The only way I can ever get it to change is to switch on TA and then off again. I did raise this with Mazda, but as usual never got an answer.After upgrading to v33, I noticed that RDS stops working after the radio song changes. I can workaround it by going from FM Radio to Nav and then back to FM Radio, but I was wondering if anyone else seen this problem.
