just got my AR3 along with some third party cables since I don't plan on using the CD-IH202 iphone5 kit. problem already, tho -- the $5 "AmazonBasics" 2-meter hdmi cable (http://tinyurl.com/3dj6sdh) doesn't fit the head unit port! the cable's end header is too fat, impossible to insert the cable into the deeply recessed AR3 port. dah!!

which ones are you folks using?

the one included in the CD-IH202 is an "automotive grade" cable, which has two features 1) designed for temperatures and vibrations found in a vehicle, 2) header designed for clips to prevent dislodging (AR3 comes with one of these clips). turns out its an actual HDMI spec:

...yet I can't find a single one for sale anywhere. has anyone seen these?

The AmazonBasics HDMI cable works just fine for me.

what's the model or ASIN # of the Amazon cable you're using? mines in the link above -- the one they shipped physically will not fit into the AR3 port...

tested a Dynex (as well as some other brand adapters) as a sanity check, they fit. 

the AmazonBasics from my link (3D, ethernet, etc) is too fat. their site has a good frontal image, but here are a couple more:
