My Vehicle has the Alpine speakers, does this mean that the radio has subwoofer output? If so, how come there are not subwoofer settings on the controls (other radios have settings like turning on/off subwoofer, volume/gain, etc.). Are there no speakers in the back area (where the 3rd row is located), or is this just a location where I could install additional speakers? Is wiring already provided to install the subwoofer in the back?

Does the Journey SXT have space in the rear, where the speakers are, to install a subwoofer? Does the UConnect 8.4 radio have subwoofer output?

What format does the Hard Drive need to be (NTFS, FAT32, etc.)?

I just bought a Dodge Journey SXT 2014. Can the UConnect 8.4 (not sure the model A, etc., it doesn't have GPS) be upgraded with GPS? Has anyone installed the backup camera (the original one sold by Dodge dealers)? If so, how difficult it is? Would installing the camera myself void the warranty? Went to the dealer and the charge $320 for the camera (not bad), but $468 for the installation (wow, way too much). Thinking about doing it myself. What is the size limit of an external HDD (Hard Disk drive), and what format should it use (NTFS, FAT32, etc.)? What about the USB drives and SD Cards, what are the maximum specs allowed (size, format (FAT32, extFAT, etc.)? On Ebay, I saw a kit, with an addon module (small box), and a connector that is supposed to be added to the radio and it will then have GPS. Price was ridiculous, $1300, while the actual radio (UConnect 8.4 AN) with the built-in navigation costs $1200). Any ideas, suggestions, or advice are welcomed. Thanks, and blessings to all.
