Yeah indeed this a gr8 product. I picked up mine from New Delhi from https://ebay.in formerly known as https://www.baazee.com
Mine is branded as "I-MUZIX" its got a powerful sound and a lovely remote with Equilizer and select song from a Folder or just a file.
I bought this for just Rs.335/- by paying online with an online transaction. I'll paste the website where our BHP Team users can buy it and I believe they do have a COD facility (Cash on Delivery)

I already had a pen drive with 4GB capacity so I pumped in all my mp3 from my PC and I was ready to go. The device has an FM frequency selector so one can set it to any frequency of their choice (eg., I have set mine to 102.70) and then you set the car's FM stereo to the same frequency and hit the PLAY button on the MP3 FM Modulator and you have crystal clear music.
Awesome solution for those who do not have a CD player and/or MP3 player in their cars or their CD players have blown and they do not want to buy a new car deck as some of these cost a bomb, while the cheaper from JVC, CARBON etc cost around Rs.4000+
It gets its power from the cigarette lighter so if a car does not this then one can get it installed for a few hundred bucks from any local mechanic.
Usually these products do not come with a warranty or may be 15-30 days warranty but what the hell... you're just paying Rs.300/-+ to get MP3 music from a bust CD player (or may be just a simple FM Radio in your car deck)
In the last 3 months I have installed over 50 of these mp3 devices in my friends', cousins', etc cars and they are running superb. Just yesterday we drove to AMBY Valley city (Maharashtra, Lonavala) and I blasted my music in my car with Trance and Rave and I had many people with Mercs and BMWs asking me what Deck I got in my WAGON-R.
BTW I got a simple SONY CDX-GT350S in my car and the CD Player constantly gives a message CD RESET so I thought of buying a new deck with a USB capability however I just spent another Rs.335/- and got this FM-MP3 modulator and I am back on the road. (I hate driving without music) I have 5 cars; Wagor-R, Hyundai Getz, Hyundai Santro, Maruti Zen and another older Maruti Zen (now with my wife) and they all have this MP3 FM modulator but the Wagon R is my favourite with Sony XPLOD speakers. However believe me with good speakers or not with good speakers the sound from the MP3 is AWESOME ..
In my wife's Zen there is an assembled deck with a cassette player and FM Radio and old assembled speakers however there is a good beat in them and sometimes when we are stuck in traffic too, even Rickshaw walas ask us what music system we have.
Trust me this is one hell of a product.
