Stereo got stolen from my Alto need suggestions

Pros : Low price, good mileage

Cons : Lack of air conditioner, power steering, power windows

As everybody knows it has become so difficult to maintain a car these days especially when it is a petrol car. I too have a Maruti Alto to be precise I own a Maruti Alto Green Std, this car is not offered with a lot of basic features too and hence when I bought the hatchback I got these features installed by paying extra, like the stereo system as it is too boring to drive a car without a music system.

Unfortunately recently my stereo was stolen when I went to the city park one fine morning; the lack of central locking did not let me know that somebody had opened my car now I realised the importance of this feature. Anyways, now I am looking to buy a new stereo for myself which will not cost me much and hence will have good quality as well I want your suggestions on this as to from where can I get a good stereo for my car. The one I bought was very expensive and at that time I was in a different city now I have moved to Indore which is a new city for me and I do not know any reliable shops too. Also there is no one who I can call to inquire as there is no friend and no relative is from here.

I need your suggestions please help me. Maruti Alto Green Std is a low priced car and returns good mileage despite being equipped with a petrol engine and that is what I liked most about the hatchback as it suited my budget too so I was not sceptical to buy it. It is indeed a good hatchback but lacks a few features like central locking, power windows etc.
