Really? How many times have you used a cell phone and been unable to make a call? I mean not just a dropped call that you redialed and it worked but completely unable to make or receive calls in an area of normal coverage under non-emergency conditions? I have not had that experience for at least 15 years now.
Are you serious? This past week I was completely unable to make or receive calls in an area of normal coverage. I live on the south shore of Long Island, NY.
AFAIK, no HDMI interface is even announced let alone available

'An Apple spokesperson told The Verge that Lightning to HDMI and Lightning to VGA cables "will be available in the coming months."'
My understanding is that the 30 pin adapter they are selling provides analog audio but not iPod control

'Apple has confirmed to Macworld that these adapters support analog and USB audio-out, as well as syncing and charging. However, the adapters don’t support video-out or iPod mode, the latter a special mode that lets particular accessories, such as car stereos and some whole-home-audio systems, display your iPod’s menus on the accessory’s own screen.'
And as a commenter in this article points out, the iPod will still play audio over these systems since that's handled by the analog interface.
some of this is a desire to manage DRM
What DRM? None of the music on my iPhone has any DRM on it! The "FairPlay" DRM was removed from iTunes store music in early 2009.
One way to make your old car run better is to look up the price of a new model.
