C-HR DAB Radio Fault

Post by Harrisdolly » Sat Dec 08, 2018 6:25 pm

I have a excel with Navigation and DAB radio.

When the car starts up the dab radio does not work, can’t change channels.

Returned to dealer 4 times, blamed for putting dash cam.

Has anything happened like this to others, been like it since I bought new in March.

Completely lost faith in toyota

No, remove dashcam. Take it for a test drive and if it's still doing take it to another dealer ;)

I have a suspician my dashcam has affected the dab reception. I plan to do some tests to be sure.
All the best

All electronic transformers/drivers can cause DAB to fail. Because of the pulse width modulation used. It has to be perfectly shielded and shouldn't put any noise on the power line.

Others had it also with aftermarket led headlights.

Yet again the Dealer is blaming me and my inability to use the DAD radio correctly.

Apparently this is by design, you must press the favourites button and then the List button to make it work and then back to favourites.

I just think Toyota are covering up the problem. They have tried everything and I’ve even sat in a another C-HR and it did the same.

Totally lost faith as my previous Auris DAB which is basically the same, worked fine and never had an issue.

Toyota must be feeling smug now, having tossed off another customer....

Dash cam can interrupt the reception from DAB+, have read more problems with activated daschcam and DAB+.
Simple to test, swich off the dash cam and if your DAB is better then... thats the problem.

Also, there seems to be an Toyota TSB update about the DAB+ reception.. new antenna and some coils for wires.
No nice looking update, you will get new sticked DAB antenna on the inside of your windscreen and the DAB rception should be better.. no really known user info about it (because its very, very new update) but just to be sure... let your dealer register the issue about DAB and maybe the upate becomes available in UK also.

If the reception is better when dashcam disconnected you could reconnect dashcam but add ferrite surpressor cores to power supply line, suggest one at connection to car 12v supply and one near to camera power input. See attached photo just wrap power cable around a couple of turns on each.
