Carista Software For VW T5
Carista is an app that allows you to customise certain aspects of your VW T5 van's onboard software. If you buy the Carista dongle (which connects to your van's diagnostic OBDII port and onwards to your smartphone via bluetooth) it gives you access to features that would normally only be available to VW dealers.
You can customise things such as one-touch electric windows, coming home lights, central locking and around 100 other things. It can also diagnose engine management problems and reset the service light.
In this video, I look at all the features. You can buy one of these by clicking this link for a very reasonable £20 and you're not limited to the number of vehicles you can use it on! - https://amzn.to/2PStxN2
