Acoustically insulated laminated privacy glass option

[Brandinimo]

The cell phone reception in my Taycan is noticeably worse in all areas compared to my other vehicles. I have thermal/noise glass.

I heard that the Acoustically insulated laminated privacy glass option can impair the mobile signal on a Taycan.

I need to be able to make & receive calls so is that a fact or rumour ? Is that special glass a good option or better to avoid on a Taycan ? Thanks for your input

Yep. Have to hang my iphone out an open window to get signal. Hopeless.

Better when on the wireless charger but hopeless handheld which you need as you can't watch videos through PCM while charging. Tesla again miles ahead here. Porsche in dark ages with PCM.

Not a rumour. It's bloody hopeless iphone 13.

I really wonder what’s going on here; some folks reporting no significant LoS while others say it is hopeless. Is it a car spec thing (pano roof vs metal roof) or a location/signal tower density thing? or mobile provider thing? or an MY production things (maybe improved it in later production)? or something else?

Could it also be whether you use car play?
Perhaps when I get in my car and my phone links to the car it uses an external antenna whereas if you use car play or the Google equivalent it goes through the phone itself?
Having written that I don't see poor signal strength on my phone in the car, though I almost never use a phone in the car so few examples of possible problem.

Your phone can only couple with the external antenna if it's docked in the armrest charger.

Differs in different markets. My Manual doesn't show either.
At Porsche on tuesday. Will get further info.

So yes, Porsche confirmed, that the charger leads the signal to the external antenna.
It doesn't really CHARGE...but I will test the signal now.

I very rarely use car play but when I do it disconnects me from the car. I had assumed when it is connected to the car it was using the car sim and antenna not the phone itself for hands free and when using car play it is using the phone itself for hands free.

Maybe not, but it seemed to be a possibility why I have no problem and others do.

Which is useless if you want to watch a video while you charge.

Or if you connect your phone to a cable so it actually charges rather than just gets heated up.....

OK, interesting point...

The PCM disconnects Bluetooth when CarPlay (or Android Auto) is being used - they both use wifi for the extra bandwidth required. Therefore calls must be handled differently.

I don't think the car's internal SIM would be used (wrong number!) but in older PCMs there was an option to use a remote SIM function where the phone shares its SIM data with the PCM then the PCM handles calls - using external antenna. I've no idea if this happens in the Taycan but it's possible.

Just speculating on why some people have problems and some do not.
TBH whilst I don't think I have problems I may only use my phone in the car twice a month so maybe I have just been lucky.

Over 1 year in my '22 GTS and no discernable signal loss with the noise/thermally insulated glass. Works like a champ.

Yes I suspect that last is key. I *don't* pay for Porsche wireless.

Perhaps the car has been designed as a Faraday cage so you are forced to give them more money.....

i do not pay for Porsche data; my phone is connected to PCM for Car Play buy i don’t actually uses it. i do have a metal roof and noise insulating glass. no perceptible phone signal difference inside/outside the car
