Question Duplicated numbers on car dashboard

[thegios]

When I connect the Pixel 7 PRO via BT with my cars' dashboard, I see for each contact the same mobile number duplicated twice.
When using car's voice command "call XYZ" I am always prompted with a list of two equal numbers and I am asked to select which number to call.
This happens with all my cars (different brands) and only with mobile numbers (if a contact has a mobile and a landline, I see three numbers: twice the mobile and once the landline).
This does not happen with contacts whose phone number is not associated to WhatsApp (yes, I have a couple of contacts that do not have WhatsApp...), so I believe it must have something to do with WhatsApp.

I think there is an option to merge contacts in the contacts app, never used it though.

That's not the problem

I think whatsapp calling is causing this, phone knows what these 2 numbers mean but for car it is 2 different numbers, differect accounts etc. For my case Audi mmi shows 2 numbers for each contact but Android Auto shows one for normal cell calling number and one for whatsapp calling number.
Fun fact; when you select whatsapp number in Android auto it really does calling from whatsapp, using no cell, well cell data ofc.

Exactly same situation and yes as I wrote it must be WhatsApp...

Was hoping for a solution ...

Well, i do recommend against deleting those numbers which I tried and failed miserable as Whatsapp quickly re sync those numbers.
Also don't try to delete contact list from car, because it is the car that does not understand which means what.
Imo Google should have a setting to what to send for bt devices. So you can select only Google contacts for car but not other things.
Btw it was worse when "meet", "hangouts" and other apps were installed. There was tones of numbers and it was so annoying.

Well I have WhatsApp and WhatsApp Business, and as you can see Android combines the three contacts Inyo one, yet I see only two equal numbers and not three.
