Thank you!Yeah, you can use the mod. It works. There were still some issues though, like turn by turn directions around town were too delayed to be useful. What I ended up doing was getting that rugged ridge dash multi mount, a cheap Bluetooth speaker, and a GoPro mount. I cut the top off the GoPro mount, epoxied the Bluetooth speaker to the GoPro mount, screwed it into the rugged ridge phone mount. After that, added a double usb charge port up there. Now the radio just is tuned to fm, and the iPhone works great with the Bluetooth speaker. This is much cheaper than swapping out the stereo, and turn by turn directions are nice and prompt and clear.
