I'm putting in a new Nav HU in my new car and trying to determine the best option for me. I've read through the forums here, the ARU thread on XDA, and on the AppRadioWorld site; however I'm still stuck on what direction I should go in. Some sort of Nav feature with BT streaming is important, but I can't decide in which direction to go.
NAV: I know the 4000 doesn't have the NAV unit included, but whereas we'll have our phones with us at all times I wondered if we can simply use either ARU or something to use and control Google Maps via our phone. I thought so, but does anyone have experience with this? Part of me wants to go with the 4000 because of the chance she might go with the iPhone at some point, but the AppRadio includes the NAV so if she gets frustrated with ARU, she would have the NAV built into the unit.
CarPlay: Apple seems to be pushing back CarPlay again and again. It was expected in July (??) and we're getting close to the September iPhone reveal with no news. Should I really consider that a selling point if it keeps getting pushed back? I've seen this with Samsung and their inability to provide timely system updates to their phones and I'm not excited about that happening again.
MirrorLink: I'm not entirely clear what MirrorLink does that ARU doesn't, but with the purchase of a new phone on the horizon I'm wondering when they will open the floodgates to other newer phones. I saw the M8 (one that I'm looking at with the LG G3 and the S5) was recently certified as a MirrorLink capable phone.
XM: I don't currently subscribe to XM, but my wife's new car has a trial and if I can put a transponder in cheaply I might do it. I see the AppRadio 3 doesn't allow for that expansion. I'm honestly not sure it is a big deal, but it should be a consideration... same with the need for a disc drive. I haven't listened to a CD in FOREVER.
BlueTooth Streaming: My wife loves this feature of her new van's stereo. Does one of these units perform considerably better than another?
Finally the most important issue is cost. The AppRadio 3 can be had for nearly half the price of the 4000. I can always sell her stock radio for slightly less than the price of an AppRadio 3, but is the future expansion of the 4000 worth the difference?
