Simple installation and works as it should, wish the conections on the actual unit locked/snapped into place though.

Excellent choice !

For my Nissan Murano 2005, it was 'the' product that i was looking for. Great integration with the OEM style of the vehicle, price that was competitive.

Great Product!!

September 5, 2016

I purchased this product for my 2005 Nissan Altima SE-R which had the stock factory Bose radio. My other car is a 2015 Q50 which has a factory AUX, when I would drive my Se-r to save on my infiniti's miles it would kill me to listen to regular FM radio. I also didn't want to compromise the clean stock look of the car by changing the deck, this product is invisible (you hide it behind the stock unit) and the quality is the same as any other aux comparable device. Highly recommend this product!

hardwire aux input solution for infinity/nissan without comprimising sound quality
Alex P on Jan 28, 2015
Can this be used to hook up an amp up to too? Or does it just let factory speakers use aux?
dustin on Sep 18, 2015
Best Answer: Hello,

It can only be used as described in the description. Therefore, it cannot help in adding an amplifier, as it doesn't have the appropriate outputs.

since this is for input into the radio want to use for IPOD/IPHONE playback.. can it be used with a PAC interface that I am currently being used for OUTPUT to my amp?
Jpeeps on Jan 27, 2015
Best Answer: Hello James,

Yes, they can be. However, It often isn't very ideal to connect multiple interfaces to one another, so please contact Technical Support for more details.
