Hi, I have a 2014 GLK250 and would like to upgrade the seriously outdated radio display to an android. I'd like to hear from anyone who has done this successfully. I have searched and searched and can't find any US companies offering this aftermarket setup. I see plenty of Chinese units on Ali express and elsewhere though. However, I'm extremely concerned about the quality of these units. The cost of the units far exceed my threshold for something that may not work right. So please, if you have installed one of these units successfully, I want to hear from you. Where did you get it? How long have you been using and are you happy with it?
