He could you post your final list of parts used and costs involved.
Is the Diode Isolator power circuit DIY or you got it from somewhere?

On a side note, I was wondering whether to mould /mount the LCD
I am a devil for details.

THe LCD would be lovely if it cold be fliped down when not needed like a laptop.

I would keep the second battery and dual battery isolator. dont try to build a DC-DC PSU it is a pain in the neck just buy one.

The Diode isolator is a DIY consisting of 4X 4A diodes and a 4700uF 50V Cap

here is a tally of the running costs:
7" TS LCD (iride.in) 11400/-
Via C7 board + processor + AC PSU + Casing: 6.5K (it was a steal, the total normally would be arnd 10-11K)
Xantrex 12V- 110 V inverter: $35
Holux 236 gps: $80
80gb 2.5" hdd: 3K
512 MB ddr ram: 1.5K
BT (widdcomm): 300
rubber keyboard: 450
Tank Circuit + Wires + fuses + misc.: 1000
7AH Sealed gel type battery : 800
Satguide map for chennai (yet to come) : 800
Google earth + Goops + roadrunner: free

~26k + $105 -> 30.5k

You are right..I don't plan to build that..not worth the time that'll go into it...
As it stands, I have already spent 1 entire weekend and then average 4 hours every night (11:30 PM- 3:30 AM) from last Monday till Thursday on setting this puppy up

Will do that after all the software is done and over with (tweaking windoze, installing satguide maps etc.)

yup, that would have been great....shouldn't be too difficult if I can find the right mount to do that...the current mount is a stick on mount and so far, I haven't cut/bezelled/dremelled any of the plastics in the car so it doesn't hurt to try new locations for the LCD

^^LOL.....that was a good one!
Anyway, the costs are very reasonable considering stand alone GPS units and even car dvd players come close to that price....
BTW wish me luck , am off to get a new HU right away since the stupid XPLOD (why did I ever buy that) i have doesn't have aux in and I am feeding the output through FM..

Planing to pick up a basic Alpine/Pioneer (2950 maybe) as I don't need any fancy features on my HU now

Ah, another thing I forgot to add in the list above is completing the phone integration piece...I haven't been able to get it up & running as yet..also need to get a trackball to keep in the centre console for the times I may need a mouse

the basic alpine (i'd recommend the 9843 of the older stock or 9812R/9883 of the newer stock) would cost 9K the Pio 2950 about 4K.

Picked the Pioneer 2950..
I like the SQ of the unit (have it on my swift coupled with infinity 9623) ..
Also the price diff. between the Alpine (10K) and the Pio (3.9K) was huge...

Since the HU is going to work just as an amp, and nothing more, decided to save a few bucks in the process

Update: I installed Google Earth with GoopS, and also the Satguide map for Chennai yesterday

The Satguide map is pretty accurate (Make it very accurate) though the routing is less than perfect..The POI (points of interest) implementation could be better too

What however is awesome is Google maps...The accuracy is dead on spot, and the cool factor of seeing the actual landscape from the top is mind-blowing...Best of all, it's totally free!

The only constraint is you can't do routing (i.e. mark your start and end-points and expect the software to chart the route for you and give you visual and voice directions)

But for out-of-town trips, it's the perfect solution

Awesome work. Dumb question, but where's the CPU casing mounted? And how quiet is this thingy?

not a dumb qstn at all...placing the CPU casing is one of the biggest problems
since i used a mini-itx mobo (which is really tiny) and a very small form factor casing, the whole unit went under the passenger seat and fastened with velcro

again, the Via processor is very low on power drain and heat so it has a tiny fan which cannot be heard at all

I think the Via processor should be good enough for media playback duties. Even phones do it, with a puny Geode or something.

I like this idea a lot; I wonder if it can also be hooked into CanBus or the ECU, and provide realtime vehicle diagnostics and control. Sort of like a home-brew iDrive or MMI ...
