Ok... Here's the essentials for the project:

DC-DC stepdown converter https://www.amazon.com/Adjustable-Conve ... B07L5J4QTD
ESP-WROOM-32 https://www.amazon.com/gp/product/B0718T232Z
3pcs MCP2515 CAN Bus Module https://www.amazon.com/gp/product/B01IV3ZSKO
POW PowerBoard Box3 Kit https://www.amazon.com/gp/product/B00W8FQJR8
10 pcs Logic Level Converter https://www.amazon.com/gp/product/B074M8TM81
gen4-uLCD-28DT https://www.4dsystems.com.au/product/gen4_uLCD_28D/ (shipping kills me, I was able to find it in US, don't remember where)

Not yet sure, but you may need an ULN2003A (one): https://www.amazon.com/ULN2003AN-Darlin ... B077X33WW9

If you are planning to upgrade your dull HU to a much better 2DIN Kenwood, you need a 2DIN fascia panel. Volvo has such a panel for 01-04, otherwise look for Scosche Dash Kit for your model year. It is not a perfect fit unfortunately.

Regarding Kenwood: I've upgraded my speakers to Focal midbass'es and tweeters along the way, and that setup sounds very nice, not that much different from the premium sound in wife's XC60.

I can also post what tools and other common parts I use to build this thing up.

I read two pages assuming I'd figure out what you're talking about......nope.

This display.

VTL is guiding us how to make are own units.

This is my "version 3" work in progress:

Need two extra CAN channels to control headrest monitors for my kids, you don't have to solder all four.

I had the software generally working on ESP32 a couple of month ago, just decided to solder everything on the breadboard and put in a bigger enclosure. The code sits in the esp32 git branch: https://github.com/vtl/volvo-ddd/commits/esp32

Also all/most model years differ in how the CAN messages are layered out exactly, so that part needs to be adjusted. The software is designed with that in mind, all the car differences should be contained to one file (car configuration). For example, this file is for my MY05 XC70: https://github.com/vtl/volvo-ddd/blob/e ... _aw55_us.h Adaptation to other configurations shouldn't be too big of a deal, I figured out how to carve needed bits out of VIDA SQL database.
