Pioneer da230dab problem

[bigdavy]

We have a pioneer da230dab head unit which is around 9 months old. Over past week it has been losing the radio signal ie the sound cuts out. It has been gradually getting worse to the point of it happening every few minutes.
Initially I thought it was just the dab signal getting interrupted but it's happening too often & in wife's newer car there is no dab signal loss.
Anyone had similar issues?
I'm wondering if it's a head unit issue & as it's still under warranty it might be worth pulling it & trying for a replacement.
Any thoughts welcome.

Check the dab aerial has a decent earth... if it's an aftermarket one that sticks to the windscreen surround for its earth, it may be unsticking.

Have you installed/use any other electrical equipment in the car? Eg, dashcam power feeds, mobile phone charging leads, etc, can cause dab signal interference.

Nothing else new in car, just concerned head unit is faulty.
