How to get Google Maps in the Taycan?

[PorscheCH]

I already have a phone mount. I was not aware that with a simple phone mount one can use a phone navi (eg. Waze) , PCM Navi and Carplay at the same time…. My guess is one cannot.
where s the magic?

Buy a Brodit pro clip so you can actually use the functionalities of your phone too. Simple. 50 bucks and all is solved.

I allways use Waze (for best route, exact ETA, trajectory controlls, cops,...) and PCM (for residual SOC at destination and battery pre conditioning) simultaneously.

Question was to use PCM and google maps. 2 at the same time, not 3.

If it’s the original question, then it is “how to use google maps in the Taycan” … so only 1 . Not 2 at the same time, then. And I suspect he meant on the Taycan’s display rather then just inside the car (yes, any phone will show google maps or waze on its screen inside the taycan, true

One of the things I like most about this forum is that it enables members to become very knowledgable about these cars. Often way more so than the public facing staff in Porsche Centres.

As a hobby project of mine is reverse engineering Porsche APIs, I thought I'd share a little insight into why the quoted sentence above isn't the full story.

Here is what I've discovered:

• The mapping data – roads, turn radiuses (used by Innodrive), elevation and POIs come from HERE Technologies (https://www.here.com). HERE is majority owned by a consortium of German automotive companies – it was owned by Nokia for a long time and traces its roots back to US-based Navteq.
• If you pay for Porsche Connect services you can activate a "Satellite View". The data/imagery for that view comes from Google, but it is layered over the HERE data. You'll see a Google logo showing when this mode is active, but it's just the imagery – all the structured data you see on the screen remains HERE.
• Route planning also comes from HERE, including destination and waypoint searching –all from HERE.
• If HERE can't find a waypoint – it has a comprehensive but smaller database of POIs than Google – you can optionally perform what Porsche call a "Online Search" for POIs. You do this by clicking on the large "G" button/logo beside the search entry box on the PCM. If you do this then the text you've entered will be sent to the Google Places API and if something is found, that is returned to you. A hybrid search between HERE and Google's POI database's is therefore possible.
• HERE routing APIs have the ability to take Google Place IDs as well as its own waypoints which is why this works.
• The HERE structured data and POIs for the area you are in and going towards is capable of being stored in the PCM for offline access. This is why you get these "Map Updates" notifications. This allows navigation to continue when in a poor cellular signal area (or external cell access is not working on Taycan – an all too regular occurrence).
• The Google Place IDs or Satellite View data is not cacheable and will not be stored in the PCM – likely for licensing reasons.
• If you are driving in a long tunnel – common enough in Europe – and there is no GPS signal, the HERE Technology is receiving wheel and steering wheel data from the car and can accurately estimate its locations inside the tunnel for around 10km after its last GPS location was received. This is invaluable for giving navigation instructions in long tunnels that have junctions inside them. Something that none of the mobile apps are capable of as they don't receive the data to do this inertial navigation.

Here is an example call for a route that the car makes when plotting a route:

Wow ?

So just to clarify the intent of the original post, yes, I was just hoping to have Google maps on the PCM, as I can obviously use my phone. I have both an Android and iPhone and Carplay works pretty well but I hate iphones and prefer Android for everything else. If they updated my 2021 with Android auto, that would solve the issue but don't think that's in the cards. For now I'll probably use carplay when I want Google maps. Despite some of the comments, it's not debatable that, in my area, the Taycan navigation is beyond terrible. This morning I compared routes on it vs Google maps and the difference in routes would have caused a 33% delay in arrival. Porsche service has been useless thus far. Insane to me that a car that costs this much has such a dismal and unreliable navigation system. Super disappointing. Thanks all for the comments and ideas!
