Read the following and be prepared to be disappointed...<br><br>Hello Richard<br> My name is Frank & we received your request for a navigation system. We have not tried to order 1 yet but they teel us they are available, so here are some prices for you.<br>#86841-47020 nav computer $4183.91<br>#86110-47040 nav display $3328.81<br>#86860-47030 nav antenna $403.14<br>This price does not include tax, shipping, or the 10% discount for internet customers<br>Thnaks for giving us a chance to serve you.<br> Frank<br>

I just received the Pruis Electrical manual and the repair manual. The Electrical manual claims the following:<br><br>N2:Navigation ECU:90980-11973<br>N3:Navigation ECU:90980-11923<br><br>These part numbers are not close to those that you received... ...happiness?!?!?<br><br>The sadness part is I used the Electrical Manual and discovered that indeed atleast my 2001 Prius does NOT have the GPS wiring from the center console to the Nav ECU's. :-(<br><br>Also discovered that the wiring for the side airbags is not there as well.<br><br>Attempted to find the connectors for the Nav ECU's within the center console but the effort seemed useless until there was a ray of hope that the Prius NAV ECU's are availiable and have the US DVD's...<br><br>...maybe you could attempt to find the price of the above part numbers... ...I guess I could just as well... ;-)<br><br>

No question...way out of line. DeLorme sells a CD and GPS antenna with all the major and minor roads in the US for $180. Add a CPU/CD ROM reader for say $1000 and as you say the screen already exists and you are finished.<br><br>Does anyone know of what they are getting in Japan for this option?<br><br>Pete

I was thinking that perhaps Toyota would go with the Alpine system, like the one Honda/Acura uses. The unit is DVD based and supposedly one of the best out there. It would be a $2000.00 option and should work with the touch screen in the Prius with some electrical engineering tweeking.<br>But I doubt that a good, standardized GPS navigation system could be bought for $1000.00 or less.<br><br>(BTW: the Alpine system is nice, it is an option that I bought with my car)

Check out the Garmin StreetPilot GPS ColorMap at<br><br><a href=http://www.garmin.com/products/colorMap/ target=new>http://www.garmin.com/products/colorMap/</a><br><br>This can easily be moved from vehicle to vehicle and sells at some web distributors for around $550. Using a serial cable and a PC, you can download the maps of interest from a CD-ROM to a RAM cartridge in the GPS unit before leaving on a trip. Some distributors are selling a kit which includes the GPS unit, North America CD-ROM, cable and 32 MB RAM cartridge for $799.95. Here's one as an example:<br><br><a href=http://www.gpsnow.com/gmspcm.htm target=new>http://www.gpsnow.com/gmspcm.htm</a>

&gt;<a href=http://www.gpsnow.com/gmspcm.htm&lt; target=new>http://www.gpsnow.com/gmspcm.htm&lt;</a><br>While I agree that portable units are readily available for much less, the Alpine GPS/gyro system can be integrated with the car.<br>In the case of the Prius, I am thinking that it could (with EE modification) be connected to the Prius onboard display. Also note that the Alpine system gives audible instructions on when to turn ("turn right in half a mile")<br><br>But again, you are right about price. It becomes a trade-off between portability versus integration along with the asthetics of each compared to price.<br><br>Robert

&lt;&lt;&lt;<br>While I agree that portable units are readily available for much less, the Alpine GPS/gyro system can be integrated with the car.<br>&gt;&gt;&gt;<br><br>For what it's worth, I think the Prius factory system is also GPS/gyro. The New Car Features book shows that in addition to GPS info, the nav CPU receives wheel speed and the output of a "yaw sensor" (i.e. a kind of quartz gyro).<br><br>Bob F

&gt;The New Car Features book shows that in addition to GPS info, the nav CPU receives wheel speed and the output of a "yaw sensor" (i.e. a kind of quartz gyro).<br>&lt;<br>This is interesting!<br>I don't think my system uses the wheel speed, instead does the calculation via GP/time (which equates to speed)<br>Now, I was thinking that Prius would be using the Alpine system because I believe I read that their system would be DVD based, and the only system that is DVD based (that I know of) is the Alpine system -- the DVD based system has many US cities and all US highways.

&gt;Mike Kaiser had mentioned on the eGoups mailing list that the GPS system may be made by Denso. See the following link<br><br><a href=http://www.denso-int.com/proto/sae2000/navigate.html&lt; target=new>http://www.denso-int.com/proto/sae2000/navigate.html&lt;</a><br><br>T\ hanks for this information!<br>This is great stuff.<br>Because it is a different company, most likely it is a different product.<br>In this case, I would like to see this GPS unit, because it looks like a fun toy!<br><br>:-)

Since Alex mentioned my post over at e-goups about the Nav system I'll add it here for those who don't monitor both lists.<br><br>I'd also add to this discussion that I think the Prius Nav System is made by DENSO becasue the Navigation Quick Reference Guide posted over on e-groups by Paul Rodgers has a DENSO and Toyota part number on the last page. Also the DENSO unit in the Lexus (a Toyota product) has a LCD display that looks similar to the Prius Display. Additionally the DENSO unit uses the Toyota Mapmaster for basic map data.<br><br>I'm sure that IF the part for a Prius Nav System are available they WILL be two or three times the cost of the factory installed option. Look at Alex's work on CC. A $250 facoty option ended up costing over $750. But I still enjoy discussing this topic. <br><br>- - Mike Kaiser<br><br><br><br>

&gt;<br>DENSO makes the Navigation system for Lexus here in USA -- check this site<br><a href=http://www.denso-int.com/proto/sae2000/navigate.html target=new>http://www.denso-int.com/proto/sae2000/navigate.html</a> &lt;<br><br>This system is looking really cool!<br>It has voice recognition, if I read it correctly.<br>Anyone going to guess what it is going to cost?

I went on the Lexus site an when thru the WWW process to build my own Lexus LX470...<br><br>First off the BASE MSRP is $61,405! Ouch! That is about 3 Prius's!<br><br>The Navigation System option is about $3000. It is bundled in with the $1280 audio system, electrochromic rear view mirror, 6-disk CD player.<br><br>

OPS! "an when" was supose to be "and went"... ...I think bed time is approaching... ;-)<br><br>Anyway...<br><br>It seems to me that if we could somehow "lie" to the Pruis that the GPS option is installed, we should be able to attach a portable PC in place of the GPS unit via what it seems is the VGA connection. If we knew what the 2-wire serial bus was, RS-232, CAN, duh?, we may be able to accomplish this.<br><br>I say the above because I do not see a jumper of any sorts that indicates the presents of the GPS unit.<br><br>Anybody know? Does ee_of_ee want to go here?<br><br>

Although I refer to myself on this group as ee_of_ee, it is related to my job title, not my degree. I'm not an electrical engineer.<br><br>Sorry, no help.
