I recently put an Xtrons unit (newest version with android 11 operating system 6gb ram 128ghd) in my 08 X5. Completely satisfied. Boots up extremely fast. CarPlay works great. No hiccups so far. Only slight caveat is Bluetooth and wired CarPlay cannot be connected simultaneously without CarPlay audio skipping. There is a warning that pops up telling you not to do this when CarPlay is started for the first time. Only worth mentioning if you connect multiple devices like a second phone or Bluetooth OBD tool. I purchased the xtrons “Wi-Fi” Obd tool for $12 and it works fine.
