I was planning on doing this after hearing about it a few months ago but now that I see it I think this is a much easier option then putting my Nexus 7 in the dash like I was planning haha.
I think I'm reading this right but it looks like an amazing deal on appradio 2 right now...
$120 MIR from an authorized dealer.
Bestbuy.com is an authorized dealer and has it on sale for 279.99.
UPDATE:
boo, no go from bestbuy but still a good deal.
