Speed camera detection

[cnprior]

hello,

New Job, 80 mile commute, lots of 20& 30 zones......
Was caught speeding on M1, recently......no argument - missed sign and there was also previous signs saying camera not in use.....but this one was live.

This morning, mobile radar on opposite side of road in a 30......might have been doing 34/35.....not sure was slowing down but,probably not quick enough.

Can anybody recommend a device which is GOOD, not bothered about cost.......but it needs to flag up audibly loud when there are mobile police radars.

Need to keep my job and a previously clean licence has been destroyed in the space of 6 weeks,

Absolutely hate this, have thought about non-detectable plates, but I've always been law abiding !!

Advice appreciated.

Thanks, I am trying to stick to the speed limit, but to be honest an hour and half commute each way, and I do wander on the speed inadvertently.

Have tried waze, but agree with comment if already over. I have a Tesla and have configured the audible warning.

Has anyone got the road angel setup? Whats that like?, used to have a Good reputation.
