Acura Apple Carplay Issues with Heads Up Display (HUD) and Google Maps on 2023/2024 MDX & Integra models (same for BMW)

I spent an hour on the phone with the Acura tech people after my local dealer was trying to upsell me to an Integra Type S confirming what I was observing. Namely,:

Heads Up Display ("HUD") while using Apple Carplay WILL NOT work with Google Maps

(but Google Maps will work on the touch screen monitor while using Apple CarPlay);

conversely, HUD with Google Android Auto WILL NOT work with Apple Maps (but Apple Maps

will work on the touch screen monitor while using Android Auto). It seems that BMW models have the identical shortcoming.

Since I have a Samsung S23 and my wife, an iPhone 15 Pro Max (but both greatly prefer Google Maps and/or Waze ), we have had front row seats to this major system flaw.

Unlike, with the Acura MDX line (and many BMW lines), there is no option for the Acura Integra & Acura Type S models to upgrade to the proprietary Acura GPS navigation system (similar to BMW's). I asked the Acura tech support if I could buy an MDX GPS Navigation model and install it on either the Integra or the Type S and the answer was no

It is inconceivable, that to use any brand's (whether BMW, Acura, et. al.) HUD navigation features, you can be forced to change your phone and, in the case of the Integra/Type S lines, not have the option of upgrading to the Acura inhouse navigation system to bypass both Apple Carplay and Android Auto defects.

I told the Acura people that this was a deal killer for me until they resolved this problem. 

BUT, most importantly, for the purposes of this discussion thread, I did not get an answer from Acura as to whether the culprit was Apple & Android for not making HUD provisions for the competing map apps OR Acura not paying/demanding that Apple/Android deploy HUD capability for competing service.

If anyone knows, please let me know so I can raise **** with the right groups. Thanks.
