Also after a while it may begin to seem cumbersome having to carry the lappy and attach/reattach connectors everytime you park the car for a longer duration.

Good luck in your endeavour
Thank You for your sugestion. Yeh I know Heat is a major factor in India, specially in cities like Delhi, Hyderabad etc. I have a plan to overcome the heat too while the Vehicle is in Move. But when it is parked in noon, we can't help it out. This is another factor I have choosen the Laptop with Port replicator. All the time I need not to connect all the cables. Just place it in the Dock and start the ingantion. All the wiring will be fixed permanently. To auto power the laptop I am planning to use the "Wake-On-LAN" feature of the laptop. I will build a circuit by playing with the "Loop Back" concept and placing two Relays. Once the relays will get the power from the Ignation, it will simulate the loopback signal and is sufficient to power-on the laptop. I will post The detailed diagram with the pictures of this clever small unit later on. First I want to do a PoC then will share in this post.

Thank You all for encouraging to do my project.

Thank You...After doing lots of research on Digital Audio, I found this unit is ultimate. It has count less features. It supports all three surround sound formats as of now, DTS, Dolby and Prologic. The Time allignment feature impressed me very much.

Yes this unit is of no use if a compatible HU or control is not in place. I am planning for C701 too. Instead of going with another HU, I will prefer the C701. It is specially designed for this type of DSP units.

I don't think there will be any issue connecting my laptop SPDIF port to this unit. This unit has three Toslink optical connector and my laptop has RCA SPDIF connector. I know I can't directly use the Toslink optical cable between this unit and laptop. But there are many solutions to over come this. One of them is a Toslink to RCA adapter, which can convert RCA signal to Toslink and vice versa without signal loss. There are also Toslink Selectors which cal take input in both the format, RCA and Toslink and output as Toslink and RCA. So anyof them can solve the purpose.

Audio Gurus : Pls guide me, if there is any other and better option which stated above. Your Help is very much appreciated.

Thank You

Hey Sys_whiz,

try these threads for the OBD questions (as well as some car PC stuff) -


1 (OBD (On-board diagnostics) for Indian Cars)

2 (PC to ECU Interface (OBD compliant cars))

3 (Car PC setup, install and some fabrication)

4 (ApexI AFC II , OBDII compliant port for Baleno)

5 (A car PC atlast!)

6 (Prototype Car PC)

cya
R

TIP - when searching TBHP for a keyword <4characters, go to google.com and search with the following string
(eg. OBD in this case)
OBD site:www.team-bhp.com

By putting a laptop in Car we can get the n numbers of features. It will act as a fully loaded ICE system. Some of the features I am listing here :

1. Media Player (MP3, WMA, Real Audio Media etc)
2. Huge Media collection in the internal HDD(No need of a CD Changer)
3. Plug and play any USB Media like External HDD, Memory Stick etc.
4. Play Video, Play DVD, MPEG etc.
5. FM Radio.
6. Satellite Radio.
7. View Pictures.
8. GPS.
9. Reverse Camera.
10. OBD - View Realtime Statitics of your Vehicle, View and analyze Engine Errer Codes, which can save you money by figuring out the problem in time.
11. Internet, E-Mail etc.
12 View Television.
.
.
.
.
.

The list can grow. You imagine it and you can get. One should be little creative to get the features. Even you can Turn your Car PC(rather I should call as Carputer) to an Automatic Climet Control, which is not available in most of the cars in India(Except few costly Vehicles) or simply control your HVAC using the Carputer.

Integrate Your Phone with the Carputer and drive safely. Just enter into the car, your Phone will be automtically connect with Carputer and you can answer your phone calls using the Car Speakers(No one Hand Driving and no fear of caught by Cops), send SMS etc.

If you own a transport company, track your Vehicle using your Carputer. It can tell you the exact position of your car, the direction your car is moving, how much KMs your Car have run, how long it will take to reach the destination etc. If required imobilize your Car sitting at Home.
.

Huhhhh...I think I can write a Book on this.....

Thank You

Hi! LBM,

What AMPs and Speakers are you using in your setup. I am going to place the order for this unit and want to make sure which AMP and speakers will be the BEST for the setup. Also are you using component for front. If you can post your complete setup, this will help me to decide on buying these.

Thank You

Warning: when LBM and hsi cohorts ask you for a budget please remember to stick firmly to it. There is evidence to prove that some people spend many times more on ICE than they initially recokoned they would.

KB! where art thou? :-)

Thank You Navin. I will stick to my budget. Because I am spending a huge ampunt on my Car PC Setup. So I will be limited to the amps and speakers, but decent one.
