After searching at most shops of Chandigarh, I have dropped the idea of JVC and decided to go for Pioneer. Reasons: 01. Pioneer steering remote controls is available at most shops. JVC accessories are unheard of. 02. JVC HUs are not stocked by anyone. Even the main distributor in Chandigarh does not stock JVC R80BT, R90BT or any other JVC except 2 or 3 basic ones. 03. Reality is that no one pays above 6-7k for a 1-DIN HU in Chandigarh and above this, people buy 2-DIN HUs. My simple demand for a JVC KD-X80BT or X90BT branded me as "internet waale bhaiya (bro with internet knowledge)". 04. Its Pioneer everywhere. Now when I asked for a 8550BT or 8650BT, 3 main distributors refused that they do not stock these high end HUs. Now, exhausted common sense says that pick something that gives you everything you ask for i.e., - Bluetooth+USB - Steering mounted remote control - 3 RCA (if possible) else 2 RCA would do as a mono amp will 98% sureity will not be added in future. Pioneer models offering these include: 01. Pioneer DEH-4590BT (~6600INR) 02. Pioneer DEH-6690BT (~7800INR) These two above are from a trusted shop. He is also recommending a 7550 model without bluetooth. Apart from this another shop is having a stock of Pioneer DEH-8550BT that he is offering for around ~8500INR. Its a big shop but I never went to him in the past. So was not sure whether to go for it or not. How can we detect that the HU is fake or not. What all are the things to look for?
