I know the nav display in the middle was mostly plug and play (I had to add a few wires for the sound). I think the nav display that replaces the head unit is plug and play as well, however you will need to add the GPS antena.

Support and map updates for both systems do not exist. For the money on the stock unit you may want to look into an aftermarket unit, start with Eonon.

 

Thanks, have a few questions so you had no sound from the radio is there a kit to make this work. Also my wife does need the nav to work just the radio and Bluetooth and strering wheel control to work. Does the screen show what music band you are playing.

 

Just for clarity this is my nav screen.

I need to add the wires from the Nav unit to the head unit to hear the sound from the nav unit. By adding the nav I did not loose any functionality.

 

I am looking to add this mazda radio to my Mazda 3, I just called it a navigation radio.

 

The unit you are looking at should be plug and play.

If you already had Bluetooth, it is a separate module and will function with the unit. The buttons should all work.

I did a bit of looking online and it appears that the SD card for the NAV is not in the head unit, it is in the storage box between the seats.

 

Thanks
