Installation was easy, but I had to resource to an installation video of another brand that was more explicative. The one from RPM store vas very abbreviated. The unit works quite well so far and the hands free and mic have good sound level. Callers say they hear me well even when driving on a noisy road.

Just finished installing the Xcarlink onto my 2005 Mazda 3 stock HU and it was fairly easy Most difficult thing was deciding where to run the wires to since I didn't want to cut up my car. Overall it works and sound good and it is a great option for someone who has an older model vehicle that does not come with Bluetooth/Aux option. The main reason for buying this unit was for the Aux input since it doesn't drain my battery as much as streaming thru bluetooth and since I couldn't find any good units with just an aux input I settled for the next best thing. The price was a lil high for me and wish it would of been cheaper but if it lasts as long as people say it will then the price will be well worth it
