Hi I have a Jaguar XF 2017 version with touch pro infotainment system. And for the past couple of months the infotainment system powers up only when the outside temperature is below 5deg celcius. If the temp is more than 5deg then it won't turn on. Couldn't able to figure out why it's happening so thinking about replacing that with any aftermarket one which is good and have Android auto. If anyone could suggest me a best aftermarket infotainment system which is good

 

This sounds like you have a connection that is bad and changes with temperature.due to flexing of plastic, wires, etc. Replacing it might work but it depends on where the bad connection is. You might just repeat the problem. When it should be "on" poke around the wires and connectors under the dash and fuse boxes. It may just come to life.
