I know I'm hardly the first to do the Double-DIN conversion, but I've been wanting to do this for a while now and it took me about 6 months to gather the parts. My installation is finally scheduled this week and hopefully all goes well, but I wanted to try to put together a quick reference guide for others interested in having this done. Parts list: 1. Double DIN Binnacle with top vent cover (2 pieces) - make sure the front piece has mounting clips. Mine didn't and I had to grab some from my local SC. I bought this used from a member here, not sure what the cost and availability is through Tesla. 2. Double DIN vents - 2 total, left and right (available from Tesla for about $30/each) ASSY DDIN VENT LH 6005494 1 2010MY onwards, Double DIN stereos ASSY DDIN VENT RH 6005495 1 2010MY onwards, Double DIN stereos 3. Double DIN front bezel frame (had mine custom built, not sure about the cost and availability from Tesla) 4. Modified dashboard - I personally bought a Lotus dash on eBay, sent it to a shop for modification, and they sent it back. Alternatively, you can have the shop I used send you a template, then you can bring the template to your local shop and let your local shop cut the dash. You can also send your existing dash to the shop I used. They will route the new opening and send it back, but then your car will have no dashboard in the interim. 5. New A/C duct - I had mine custom built, again not sure about the cost and availability from Tesla. 6. New A/C foam pad - custom built 7. Airbag cover clips (4) - available from Lotus dealers and parts shops. Part number B121U0117F. One bag has 2 clips, so order 2 bags for 4 total. For my headunit, the CarPlay compatible Pioneer NEX-8000, I also needed a bunch of cables, including a lightning cable (got a black 6 foot one from Amazon basics), Apple lighting Digital AV adapter, and a Pioneer USB lightning interface cable. I also bought a Pioneer 2DIN Installation kit. I'm sure whatever unit you end up installing will have its own unique requirements so I won't go into detail here. Pictures of the parts are below: Overview: Double-DIN binnacle front, vents, and binnacle top vent cover: Clips for the Double-DIN front piece: Missing clips: Clips attached: Double DIN frame: Custom A/C Duct attached to modified dashboard (on a side note - my Roadster has the executive leather option and while nice, this was a huge pain. My original dash is wrapped in leather, so I had to get a custom leather wrap on my modified dashboard for a significant extra cost.) Custom A/C Foam piece: Airbag cover clips: Pioneer 8000NEX Installation kit: Various cables: I know Al and Ed's in West Hollywood has been doing this conversion for years. I almost went through them, but the cost and hassle of auto transport from Phoenix and back was cost prohibitive. I ended up using a shop called Concept:Carbon in Cincinnati, OH for many parts. They're a bit slow to respond to e-mails, but they will eventually and the work and support is solid. For the labor of modifying the dash, fabrication of the custom carbon fiber duct and front bezel frame, and A/C foam piece, I paid $350 + shipping. The owner has since provided me with detailed installation instructions with pics to give to my local installation shop as a guide, but he asked me not to publish these instructions in a public form because it is their custom work and instructions provided to their customers. So, I'm going to respect his wishes of course. As a reference, Tesla quoted me about $5000-$6000 (I think $5800?) for just the labor to do the conversion. I'll try to add pictures of the completed conversion once it is done. Let me know if anyone has any questions or feedback in the meantime. I hope this is helpful.
