DonShockley, I really appreciate your time to answer and the chance to give me a hand if necessary... that's "gold". Unfortunately, I have "0" electric knowledge. I wouldn't mind messing up an old radio —I studied software engineering, so some familiarity with machines I have— but my new car, no way
I love the Connect, but I'm disappointed on how basic is without options and, as you mentioned, how difficult is to add options if they were not installed originally. The USB is one example, if I wanted this in the original place (arm rest), I would have to change the whole arm rest because there's not even a whole for the USB.
Beyond the wiring, I don't even see an exterior plastic cover where the parking aid sensors would be installed... everything is "you got this, period". Can't complain, I got a great deal because this was a 2014 sleeping in the dealer for a year... so... WYSIWYG. I wouldn't probably get alloy wheels like this one have, instead I'd get the sensors and a lift gate, but we're happy and we saved a few thousands.
Thank you guys for helping out. I'll touch base for advice if I decide to get aftermarket sensors.
