Reddit mentions of Belkin MIXIT Right Angle Tangle-Free Flat Auxilary Cable (Red, 3 Feet)

Here is a video I made demoing my NC Nexus 7 install. It is very basic now. I wanted to see how little I need to get audio working. It isw working better that I expected. Let me know what you think or if you have any questions.

Edit 1:
Parts and pricing(includes shipping) list:

• 2(you only need 1) of these 12v to 5v converter - ~$13 for 2
  
• 1 Right angle OTG cable- $5.75
  
• 1 Male to Male USB cable - $5.00
  
• 1 Metra Din Kit - $21.12
  
• 1 Right angle AUX Cable - $10.43
  
• 1 Female to Female aux coupler - $4.33
  
• 1 Male aux to female RCA cable - $4.50
  
• 1 Male RCA to speaker wire cable - $9.36
  
• 1 Metra wiring harness - $13.37
  
• 1 Pack Command hooks - $9.00
  
• 1 Anti-glare screen protector - $5.95
  
  Total: $88.81 + the cost of a Nexus (2012) which is about $150-$180 depending on which configuration you get. (Note: Timur's ROM only works with Nexus 7 2012)
  
  So $238-$268 grand total.
  
  I also bought a wire stripping and crimping kit - http://www.amazon.com/gp/product/B000K7GRCI/ref=oh_details_o09_s00_i01?ie=UTF8&psc=1
  And a Dremel for cutting the metra bezel and the command hooks
  
  
  I also rooted my Nexus 7 and installed Timur's rom. That was a headache and not needed because you can duplicate the functionality by using Tasker, a Nexus 7 task scheduling app. But to install Timur's ROM basically you need to unlock the bootloader, install TWRP recovery, then install Timur's USB Host ROM. That ROM gives you the ability to plug USB devices like thumb drives into the Nexus 7. It also gives you the option to put the tablet into deep sleep when you turn your car off.

Just had this issue with my S5 in my 08 Tx. Easiest solution I found was buying the two items below.
Basically plug the aux into the bluetooth adapter and have your phone auto-connect. I've really liked not having my phone tethered to anything, also I can use any other device that will hook up to bluetooth.

Edit: I like this option because there's no modifications.. it's all plug and play. It may also be the cheapest... Although I did have to extended the little button on the end of the griffin bluetooth adapter.. it wouldn't reach the bottom of the cig outlet for some reason. I just used a little stainless steel sleeve from a bicycle cable and crimped it in place a little bit.
