There’s some stuff you can access through the secret menu on the sat nav. Hold cancel + map/guide + menu. That brings up secrecy menu no.1, then hold menu again for secret menu no.2 Imgur link here to some pics of the TMC stuff in my car, you can see TMC is erroring for me.
My traffic stuff hasn’t worked since I got the car, but quite a few roads near me built after 2017 don’t show up, so I’ve never bothered with it and just used my phone. Shame because the voice is excellent.
No sense at all. Too scared to clear soft and hard faults because maybe then it will not work at all!!!At least it still gives me a route etc, just no longer showing hold-ups. TMC checker was 0, then slowly crept up to 8 over about 5 seconds then back to 0 again. No idea what that means.
