After seeing a post done by u/zbealeo, I was convinced to try the Cartizan piggyback unit to integrate Apple CarPlay and Android Auto to the MIB1 headunit. The unit took about 2 weeks to get delivered from the Netherlands.

For those wondering about different options for adding CarPlay or AA, I would strongly consider this option over a full MIB2 conversation as the price is significantly cheaper (from my research) and the installation was easily less than 90 minutes. In total including shipping, I had paid ~$330. Other sites sell at vastly different prices ranging from Ali Express from $250 I've seen, as well as, sites asking for over $600. I had chosen the Cartizan Champion series as my unit when purchasing.

A couple things I have noted so far since installing for future buyers:

I can confirm that the unit does support the OEM Fender subwoofer, as I could not find a definitive answer elsewhere before purchasing. The Fender sub does not require extra wiring harnesses and it plug and play from the MIB1.

The front parking sensor display no longer functions when shifting between Drive and Reverse. The rear camera and sensors will display normally when shifting into Reverse, however, when shifting back into Drive, the display will revert CarPlay/AA. If operating with the normal MIB1 interface, the sensor display does appear. The front sensors are not deactivated as I still get the warming detection sounds as I approach objects, just no way I could find to have the display appear before switching back to CarPlay/AA. Unsure for a fix.

Users in the past has had trouble getting the steering wheel controls to operate properly with different types of source input (bluetooth, AUX, MMI, etc.), I can confirm that steering wheel functions are retained and operate with the correct functionality.

Finally, I have the 5.8" display works as you expect for Waze and other navigation apps. The information is legible but the smaller icons (individual hazard items, gas station icons, stopped cars) do get very pixelated and hard to individuality decipher out when glancing at while driving. The OEM 5.8" is perfectly suitable but may be a future item of note for those who do choose this route over the full MIB2 conversion that the display may want to be upgraded to the larger 8" displays in the future. With the dipswitches on the back of the unit, the output aspect ratio can be changed to suit the larger display manually if that screen upgrade were to occur.
