Has Kenwood fixed issues like these in the DNX771HD in the updated DNX773S?
Cumbersome/non-logical/unintuitive menu system, for example try finding the buried navigation voice prompt volume control when she starts screaming after a loss of battery power.
Phone apps that integrate the phone to the system not being updated and becoming non-functional in current IOS/Android versions
Updates to the Nav (cost and flaming hoops to install them).
Complications of swapping between phones.
Lack of a real "night mode" tied to vehicle lights.
Tempermental reverse camera.
menu system seems intuitive enough, i have yet to crack open the manual to try to find something or how to do it...the only things that i've struggled to find is how to turn the screen off for when im driving at night. most other things have been pretty easy to navigate to.
not sure what you mean by phone apps, like the kenwood apps on your phone, the apps on the deck, or the apps on my phone that are used on the deck? lol, i basically use android auto for 90% of everything i do, so all of the apps are stored on my phone, not the HU, should never be an issue with updates.... as far as i know the kenwood apps for my phone are just for a remote and screen mirroring, i have no need to do that so i never fool with it, same for things like the pandora app on the hu itself, why bother with it when i have pandora and two dozen other music apps available to me through android auto? plus everything through android auto is activated through voice command, way easier to just ask google to play x,y,z than it is to fiddle with the deck and open the various apps manually, that's true of any deck, voice commands are the way to go when your driving, for sure....
i've only had to do one nav update, it was free and took about 15 mins, i suspect future updates to only take 5 mins, the hoops you need to jump through are: have a blank SD card, D/L garmin software, run software on PC with black SD card inserted, take SD card and insert to deck, pick update software from menu and away you go....future updates don't require any further downloading from garmin, you just put the card in, run the program and put the card back into the LX...was simple enough... and free..
swapping between phones? not sure what you mean? the HU can run two phones paired consecutively, do you mean swapping between those two phones or do you simply mean adding new phones and removing old ones from the registry? when two phones are paired consecutively there's a little display that hangs out in the top left of the screen that shows you this, you just tap on it and pick which one you want as the call active phone, both phones can play music and such with out needing to be fooled with...it's really nice having a couple of phones paired to it, so my wife and play music from her phone while I'm driving and if i get a phone call the system mutes her music on the deck and picks up my phone call for me... so while im not really sure what you meant there, that's how it seems to work.
yeah, nightmode is a bit tough, i think i messed up the install as the dimmer doesn't work, or maybe this is still an issue, i don't know, i do know when i did the install i wasn't quite sure which dimmer wire was the right one and made an educated guess, so there may be an actual issue with the wiring on my part, on the other hand with you saying this is could just be the deck as well, i really don't know, i do know that i may have to pick up the manual after all as for the life of me i cannot figure out how to just turn the screen off, i don't like the screen on when i'm driving at night, dimmed or not, just like it off, haven't been able to figure out how to do this yet, but also haven't tried it while sitting in the drive way either, so not much time dedicated to it yet....so yeah, i can firmly say that function at least isn't intuitive.... i do know there is a night mode when running android auto, the screen doesn't dim or anything but the color scheme changes,so yeah, that might still suck/be an issue.
i never installed the/a back up camera, didn't have one stock and didn't both ripping the truck apart to run the wire. could still be an issue.
so there's my experience with this HU on those issues, but i really think it depends on how you use the thing as to what issues you have and if they are fixed or not, as i said, i use driod auto like 90% of the time and it's all stuck on my phone, everything from that stand point has been great, i really cannot comment to heavily on the native apps and functions of the deck as that's not how i use it to be honest, the pandora apps and the rest on the deck itself could suck and have problems but since i just use all of the apps and accounts on my phone instead then i may never come across or see some of the issues you have.... i just know this is the most expensive deck I've bought in the last 15 years and I'm very happy with it for how i use it and have found it to be pretty easy to use and intuitive in the layout and functions of the deck that i do use.
hope that helps in someway.
