I agree! I feel like we're kinda limited with head unit option. The atoto was great for me. But I ended up building my own double din head unit using a raspberry pi 4! I added a high quality dac module, dual monitors, 4g lte, and much more.

@@seanwatts392 Nice when you know how. 👍

I run an ATT sim card in my S8 with no issue in the USA

​@@JohnWishon_Riptide9 Thanks for the info. Did you do anything special to make it work? I would love to find a solution. I spent about 4.5 hours on the phone with AT&T tech support spread over a couple day period with no luck. AT&T tells me, that for whatever reason, the device is being recognized as a 3G device which is no longer supported in my area. The network has all been upgraded to only support 4G and above. Just to see ... I tried a T-Mobile sim. It worked plug and play.

@@gibsongtr Nope just put it in and it auto selected the correct APN and worked right away (using a ATT hotspot sim from NomadInternet)
