All L462 with Touch Pro system and connectivity package (SIM card slot) are getting CarPlay and Android Auto for free. If still any of you do not have it, please ask your dealer for the software update to the latest (currently it is S21A.10....., so it is basically 2 months old). On top you will get software-over-the-air updates, so you do not need to visit dealer to get latest Touch Pro, but if your car is connected to the Internet (WiFi or Mobile network), you will be notified about new software available to be downloaded and installed
I've been using CarPlay for quite some time in my 2017 HSE Lux that we picked up used back in March. Generally happy with the experience. However, this weekend I tried using it while the battery on my iPhone 12 Pro Max was low. The experience was miserable. The device kept connecting and disconnecting from CarPlay every few seconds. The charging icon on the phone was flipping on and off as the phone would connect/disconnect. Charging the phone overnight and then trying again in the morning with a mostly fresh battery, all was well. My conclusion is that the USB chargers in the car are not able to keep up with the power demanded by the phone while also carrying on a CarPlay connection. Anyone else experience this?
