Well, my idea was to buy a tablet with unlimited Internet access plan either way (so no tethering). A cost of maybe 40$ a month does not bother me much, but for people that do not want to pay for that, they just turn off the internet access.

Point being, if one were able to switch between your operating system and the normal android system, that would give more flexibility without any disadvantages (but correct me if I'm wrong)

My plan is to replace the head unit with the tablet either way so that would go in the weight savings department. The weight of the remaining stereo is of course a compromise unfortunately.

* MP3 player functionality added *
* 16 GB storage upgrade added *


You'll have to load your MP3s from a computer/laptop whatever, but once they are there, you're good to go.

Internet: That will be a different / more expensive unit, and will require some programming on unlocking the carrier and baseband modems so it works internationally. I'll take a look.

done any looking into how much the bus is currently utilized and if all this polling may have adverse effects?

We're working our way down to ECU protocol level, but I doubt that we're throttling engine management signals on the hardware considering how fast the bus speed is vs how ECU response isn't. We'll check it but we've experienced zero issues whatsoever.

Working on mounting solutions, debugging OBD2 data-acquisition device, prepping to test with iMFD signals, roadmapping an alternate version with internet access. I should have a version ready to test on the Club Lotus Northwest (Portland OR) group in the next week.

Interesting. I've been fudging with something along these lines on my own, but not as an additional display panel, but instead a replacement for the stock gauges. Currently, doing the low level stuff, like trying to reverse engineer the protocol that comes into the instrument cluster, which seems to be based on CAN/OBD-II, and has a hell of a lot of info on it (such as wheel speed sensor pulses). I don't want to use a generic OBD-II dongle, but something which is wire-attached to the gauges and not dependent on wireless links which can be easily interfered. Currently playing with Nexus 7 tablet to this end, but I don't like using Android, since it takes too long to boot, and the power draw is too high to leave it powered on while the car is off.

Edit: Good luck with your project! It's about time we have some nice electronics options for these cars.

Trying out a vent-mount configuration. Seems to be sufficient room for access to the wiper stick.

Looks good. Just out of curiosity, do you know the brightness of the screen and its visibility in daylight? I have been looking for an appropriate tablet, but few have more than 350-400 cd/m2.

VERY interested in this project, but given the size of the cockpit of the Lotus, and general mounting options in most new cars, I'd rather it just replace my radio. Any thoughts on basing your design on a product like this? Double DIN Android 4 0 Car Radio DVD Player 3G WiFi BT GPS Navigation Head Unit | eBay Personally, I would want the unit to not only have the features you are describing, but to also have general Android functionality like Google Maps and Rhapsody, email, etc. I'm thinking more CarPC than Vehicle Display, but it seems like you're more than capable of programming either. It's late, I'm tired, and my ADD is kicking in so none of this may make any sense, in which case I apologize =)

How about consider to replace the main dash, once for all?

NoFear, it already features GPS navigation and mp3/music playback. And that double din monster looks like it weighs a bit more.

Experienced manufacture error on PLX device, burned out, so I'm adding a torture test for the hardware.
