Hi everyone, I am in UK and have a 2011 E350 with Comand NTG 4.5. I could update the maps but I would rather install a dongle or something similar to allow me to use Google Maps and/or Waze etc, via the existing screen rather than just sticking a phone holder somewhere. There appear to be an awful lot of options on the market ranging from a £2.50 stick through to replacement screens for hundreds of pounds. I have no doubt there are plenty of individuals out there who have already gone through this process and have a wealth of experience/knowledge that they are just bursting to pass on. I would be grateful for as many do's and dont's as possible so I get this right the first time. Thanks in advance, John
