Pioneer AVH-W4400NEX Bootloop

One year and four months after purchasing this Pioneer unit (four months out of warranty), it stopped working and showed this boot loop symptom. The unit was repaired at Northstar Electronics Co. (https://www.northstarelectronics.ca) for $270. They replaced the SD storage card to fix the issue. As was explained to me, it is a proprietary SD card that is cannot simply be replaced with a regular off the shelf sim card.
