In response to Needsdecaf's question in another thread about gauges (<A HREF="http://forums.swedespeed.com/zerothread?id=58796 " TARGET="_blank">http://forums.swedespeed.com/zerothread?id=58796 </A>) I thought I'd put a bee in me fellow Volvo-owners' bonnets with this:<p>Here's the general concept: Use OBD-2 to drive digital gauges displayed on the NAV/RTI screen. One could show: RPM, VSS, IAT, ECT, Timing Advance, etc, (I don't think you can show boost since non of the OBD-2 tools I know of understand how to get into the Volvo-specific PIDs for boost).<br>This is no small project, so in general here is what you'd need:<br>- you need an OBD-2 interface and software with gauges (<A HREF="http://www.OBD-2.com" TARGET="_blank">http://www.OBD-2.com</A>, <A HREF="http://www.myscantool.com" TARGET="_blank">http://www.myscantool.com</A>, <A HREF="http://www.palmerperformance.com" TARGET="_blank">http://www.palmerperformance.com</A>, <A HREF="http://www.vitalengineering.co.uk" TARGET="_blank">http://www.vitalengineering.co.uk</A>, <A HREF="http://www.auterraweb.com/" TARGET="_blank">http://www.auterraweb.com/</A>, etc.)<br>- you need a PocketPC or Windows PC (running on a small laptop), or a Palm<br>- whatever hardware you choose (laptop, PocketPC or Palm) needs to have VGA output (or composite video output) and needs to be able to run at the native resolution of the NAV screen (I don't konw what it is but it's not the most readily available standard res.)<br>- you need to interface into the NAV/RTI screen, this can be done with a hard-wired interface commercially available or through the HU-8XX using Mrg. Ed's fancy new interface (we're still all anxiousely awaiting the release of this silver bullet device)<p>Regarding choice of OBD-2 scantool for this project, I believe VitanEngineerting or Auterra would be the best since they both offer a PocketPC version and better yet VitalEngineering offers Bluetooth connectivity. Vitalengineering offers a version for Windows Mobile Smartphone in which case you could skip interfacing with RTI screen and use your phone's screen!<p>ps. I'm working on a group by for a OBD-2 scantool that supports the new CAN bus found in 2005/2006 Volvos. Stay tuned for more details.<p>LTA

Re: Digital gauges on NAV/RTI screen - conceptual (LTA)

Hi LTA,<p>Here's a link to adam3914's page showing a "plug and play Volvo navigation video input " <A HREF="http://mail.rochester.edu/~ak009m/volvonav2.html" TARGET="_blank">http://mail.rochester.edu/~ak009m/volvonav2.html</A> He also made several posts on Swedespeed about this project.<p>About 2 (?) yrs ago somebody else got ahold of a the Volvo TV adapter (PAL) from Europe and installed it in a US vehicle. There was a lot of good info in the posts if you can find them--unfortunately, I don't have a link for you, maybe somebody else can help here.<p>mgr_ed is getting closer to a shippable version of his adapter. As with any new product he is working through typical production and scale up challenges, making some design upates to resolve problems discovered in the first beta product. So, it's a little slower than we'd like, but he tells me that he is making good progress. Mgr_ed is thorough and committed to a quality product. <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0"> <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0">

Re: Digital gauges on NAV/RTI screen - conceptual (MrTippy)

Hello Mr. Tippy,<p>Thanks for the great link to adam3914's site, I'm surprised I have not come acorss this before. I really don't think I'll take on this project it was more of a way to inspire others to take it to the next level. But now that's I've seen adam3914's site, I feel excited about the possibilities for a back-up camera display for my XC90 and a laptop display for my S60R.<p>I'm anxious to get mrg_ed's adapter when it's ready.<p>LTA<br>
