I have 2015 2.0 tdi vw golf

I can’t use apps and voice, as I need activation key. Would like to use apple play on car and voice commands for phone. Been told It cost about £400 from vw, and a cheaper sd card from vision coding voids any warranties. 
want to be able plug phone in for charging at times and use wireless at other times. Looking for cheaper options 

can you please help or direct me to someone who can. 
thanks Dave

I recently purchased a used VW Golf 1.5 and when I contacted the dealership (as they have to be the ones to use the software unlocks) I was quoted £200 for apps unlock and a FURTHER £380 for the voice unlock. So nearly £600 pounds for what, in all honesty, I consider a minor addition to use Android auto and limited voice commands. When I researched this I found that that there are on-line companies who will send you the appropriate usb stick to fully unlock your infotainment system. The cheapest I have seen was £100.

I have had the car about five weeks now and I am still thinking it over because it is a great car as it is and in all honesty as it is a 2018 registration the tech inside is older anyway, for example it requires a 3G network and can't connect now that we have moved onto newer network standards. So sometimes it is best to accept that the cost/benefit sometimes is not worth it.
