Infotainment System Bootloop - Replacing it


My car recently developed the infamous infotainment system bootloop (interestingly it seemed to be caused by hot temps instead of cold). We tried unplugging battery etc. to fix it but nothing worked and none of the previous links to firmware seem to work any more, so we took it to our dealer, who said we need to replace the head unit. The shop at this particular dealership is renowned for its laziness and stupidity so I am not sure whether to trust them. Since the head unit costs more than $1.2K I am thinking of buying the head unit at a discount online and then just taking it to a car stereo shop to have it installed. Has anyone ended up just replacing the system in this situation? I just want to be sure that the head unit is the correct and only piece to buy, and that I wouldn't need the control unit, control module, etc. instead. Thanks for any info.

Check out this video below. The head unit may not be the issue. Looks like the Mazda3 has similar issues with the infotainment system.

Exclamation Just replaced mine...

Found a vendor on eBay that was parting out a wrecked 2016 iA and was selling the CMU unit for $115. Pay no attention to the Mazda 3 video about pulling the entire dash apart! There is a panel in front of your display and one behind. Pull these two covers, there are 2 bolts holding the unit down; remove them. The entire unit with the display attached will slide out. Disconnect the cables (perhaps mark them so you can get them back in the correct place - although they are all keyed to only fit one jack). Check the part number on the bottom of the unit - mine is: DD1B 66 9C0A. The new one was a few months newer and had a part number of DD1B 66 9C0B - swapped the two and voila! The system booted up immediately! Easy swap! The Toyota dealer estimated it would be $1200-1500 to replace! Really? For a 5 minute swap?

Looking for a vendor that takes units to be refurbed and thinking I may be able to get a few bucks in exchange for my used unit...

Well worth the time and effort! Best to you!
