 I have had several Mercedes prior to this one. I loved my E350 and leased the E300 when that lease was up. I am completely disappointed with the entertainment system. I am somewhat of a techie so I usually enjoy playing with complicated systems. Not this one. I dropped Sirius and signed up for the Internet hotspot figuring that I would use iHeartRadio instead. Big mistake. The car kept losing the internet signal ("Connected; No Internet") even though I was in densely populated and internet active parts of the Northeast. It took too many scrolls and pushes to get a radio station - forget about changing stations even as the passenger. Changing between cell phones for Bluetooth is another disaster - everything takes multiple swipes, scrolls, etc... Ridiculous. I'm dumping the Internet hotspot and signing up again for Sirius because it is the lesser of two evils. Even playing Amazon Music from my cell phone via Bluetooth requires too much work. It's a shame. I just leased a GLA250 (much less expensive starter SUV for my mother) and the entertainment package there is much simpler and much more basic. The good news is that both the driver and passenger can use it without thinking that they will cause a crash. When my lease is up in 1.5 years, I'm not sure whether I will lease another MB if the Comand package remains as complicated -- and dangerous -- as it is now. The rest of the car is fine and lives up to the standards I expect from MB. The entertainment system, however, is a huge dealkiller.
