After many hours of careful research, I purchased a 10.25" Xtrons Android Head Unit for my 2013 BMW 320d GT F34. There were many other much cheaper and better spec versions on the web of course but I decided to go for quality not price. After ordering, I was impressed that “Stella” emailed me to check that I had the correct unit for my car, so far so good! I was even tempted to fit this myself but used Xtrons' recommended installer Philip in Langley, Slough. I was really looking forward to this upgrade for my Satnav and Infotainment System, I have the older 4mb ram and 64mg rom version as that was all they were offering. After trying to fit this for me on Friday 11th April at 15:00 the engineer Philip, said "I think you've bought the wrong unit" this one does not integrate with your car! He is the Xtrons recommended expert, so I believe he knows what he is doing. I now have a very expensive lump of plastic in my boot and am awaiting the result of his "chat" with tech support in China. Now I am not happy with Xtrons at all. I wasted the two hours driving there and back and 1.5 hours with the engineer, what a disappointing afternoon! I really wanted to give Xtrons and Philip a great review on here, but currently I am unable to do so of course! Time to test their customer support, is it going to be any good after all. What is going on Xtrons? Tony
