Review: Reliable or Not - It is quite early to ascertain whether spending 4000.00 INR is worth or not since I have started using only couple of days. On day one there was no problem everything was perfect, tried to connect with 3 different mobiles all worked fine, able to take calls, stream music, play FM and so son (one shortcoming in the device is, at any given time the device can be connected to only one mobile and need to switch of phone BT to connect another mobile which is really a problem while more than one person is using the car. But a single owner car this is not an issue). But subsequent day it stopped working and unable to stream the music though the BT is connected properly. Then I unplugged and plugged again to use a new phone which was not paired earlier and device started working with all the devices. Today is third day and i did not get a change to use. Another major issues are connecting mobile for charging, playing music from SD card or USB drive is not as easy as we think since all the slots are cramped and unable to easily to plug. May need to wait for some more time to get the real feel, till then the fingers crossed....
