Installation: I had checked with Auto shop at Bangalore and they had no idea about Carpenter and i felt they were not interested to do the job.
Then i went to top car at Jayanagar, they were little more inclined to do the job. It took 5 hrs for complete installation, i mean everything from system, speakers to gps, obd etc.
i've Windows 7 running centrafuse and "all is well"
For the power, I've connected computer with the double din stereo power sockets and amp to battery.
I'll upload some pics once i reach home.
