Looks like the OP went AWOL, but no matter, I feel like rambling anyhow....
I have an '11 Nissan and ordered it with the special Rockford Fosgate sound package. It came with a nice scrolling display (non-touch) which worked nicely with my iPod Classic, but had a few annoying quicks. For instance, while playing an album\song you can simply go up one level to the list of other albums by the same artist (as-is normal behavior for an iPod). If you happen to power-cycle the unit it will continue playing where it left off, but attempting to navigate again will put you all the way back in the root folder at the letter A. Not the end of the world, but annoying if you have an extensive collection as I do (especially if you were playing an artist in the letter T). My previous 2008 aftermarket unit
had no such issue.
I later came to find that the "Rockford Fosgate" aspect of the sound system only encompassed the amp and physical speakers. The head unit --while carrying the Rockford Fosgate badge-- was made by some unknown 3rd party, and had virtually no information available. Multiple inquiries about a possible firmware update (both in person and over the phone, multiple dealerships) yielded nothing; generally a look as though I was speaking a foreign language. While I'm sure there's something in the fine print, they're pushing it pretty far to sell a "Rockford Fosgate Sound System" and then give people a rando 3rd party head unit. Not just that, but with a false label on the headunit to boot.
In any case, I eventually replaced the head unit in mid-2017. While I'm sure high-end luxury cars are probably worse, it was still an exceptionally difficult install.
- Regular wiring harness (in this case, mostly just power connections, dimmer, and a few misc)
- Standard RCA amp connections (easy enough)
- Had to tap my own ground into the frame. (For reasons I can't explain, this wasn't in the standard wiring harness. Not sure how the factory radio grounds itself)
- Wire from new unit to power antenna (signal boosting, not physical movement), same wire also to amp as power-on signal
- Parking brake monitoring wire, need to access firmware update and additional settings (Yes, there are defeat devices, but each new radio revision breaks them; it's a constant game of cat and mouse)
- USB to proprietary adapter, needed to utilize the factory USB connection in center console
- Steering wheel controls. Requires it's own interface module with unique wiring and programming for each setup. Probably the most difficult step, and still not working quite right. Likely needs a specific standalone resistor installed in-line
- Removal of standalone bluetooth transceiver from underneath driver seat. Bridge 8-10 wire connections from the bluetooth harness under the seat based on arcane instructions (cannot be done from stereo side)
- Install and run wire for standalone mic included with radio (couldn't figure out how to use stock mic in vehicle)
- Physically make everything fit behind the head unit, along with the dismantling and reassembly of half the dash
So yeah, safe to say it was a bit of a rough time. Sorry for the rant.
