Just wanted to post my experience with DigitalWorkz Navi Delete (radensb)
I would say everything went smoothly except for making the harnesses. If you have no experience doing it, then pay someone else to do it for you.
I ended up installing an Ipad Mini slider kit and Pioneer 7600nex 9" float screen.
I really thought hard about going with a Android HU, or Brainiac but for the things i wanted this seemed like the best solution for me.
After 12 years of living with the Bose system there were some things I was accustomed to and not willing to give up.
1) Warranty - a lot of mixed reviews on Android HU and issues with SQ.
2) Ipad - Flac/Hi-Res music (SQ)
3) Back-Up Cam
4) All Steering Wheel Controls working
5) Split screen (Ipad Ecutek Gauges/Music/Map/phone info)
6) I'm not a fan of streaming so didn't really care about that, but i do like Android Auto for voice commands. Alexa is another plus on the Pioneer and i had to have Wireless Android Auto.
My workaround was fine for the last few years but i wanted a cleaner look, and I've always felt i was leaving "something" on the table with the Bose HU.
I went from this:
I used the ipad as a hard-drive to store all my music, and stream if i wanted with any of the apps installed connected through a lightning to 30pin adapter. As much as i hate Apple products, i just really like the ease of use of i-tunes versus trying to get music on a android device.
I also used the Ipad for updated maps/navigation if i needed. I would have kept everything as is, had I been able to just install the ipad over the stock screen and have my ac controls show up on the ipad but that was not an option.
I had to install the Pioneer unit outside the leather surround as the buttons on the left would be covered. Someday i'll have someone recess the screen and cut up the surround, but my skills are not up to the task.
An 8inch screen would have been perfect but there's only one and it was out of stock everywhere and did not come with Wireless Android Auto.
I thought about mounting the stereo screen where the Ipad Mount was located but it's just too tight with the AC vents, there are issues with the left buttons on the headunit screen and it looked more out of place there on the outside.
I also purchased a 4660Nex Double din unit originally but it looked boring and out of place next to the ipad screen and i just really liked the screen resolution on the 7600.
The ipad slides out and on docks and is held in place by the glued dock connector and right surround.
For the Navi Delete board, DigitalWorkz has thoroughly explained everything on his site and the instructions are very easy to follow once you get the harnesses out of the way. His support and willingness to help answer questions and guide me have been more than anyone could expect.
Flashing the board was a little intimidating to me but after he created the walkthrough video it was a breeze.
As for sound, there's a a noticeable upgrade compared to the stock bose HU. I was able to obtain a clean signal and create RCAs from the HU to my DSP, but i had my DSP and amps gains as high as i could get them without introducing any distortion and now i would say the Pioneer is able to take some load off the equipment and producing about 20-30% louder sound.
