    danger Kenwood DNX9980HD not reading SD at times

    Okay I guess I could PM Paveli, just thought someone else might have them as those links seem to be long dead (and pretty sure he posts on other forums where the links are the same/dead unfortunately). I'll give him a PM and hope he replies.

    That thread looks like it's for "old" map requests...is 2016.10 considered old now? I thought it was the latest for NA. Has 2016.20 been released or leaked already?

    Damn that sucks Hmm well I have a total of 3.9GiB on the internal flash of my unit I think (after deleting most everything I could, there's 3.65GiB free and 256MiB used). So I think I can fit the entire map IMG on the unit itself. I've left the SRD files in the directory on the unit; I can still place the ASR/SRX files on the SD card though, right? That will still work? I still don't know if my unit is only having a problem reading the SD on startup 'cause that's where the maps are or what it is. But I guess I could try the main map on the unit and then JCV, POI, and ASR on the card and see if it reliably reads it at boot. I'm really pulling my hair out over why it behaves the way it does but I guess I should make a separate thread about my issue.

    Try that. Also, you could try the ASR files from [Only registered and activated users can see links. ] of the earlier thread for 2016.10 as they will probably work with this 'revision version'.

    [Only registered and activated users can see links. ] means 'Old' in the sense of 'old map links'. 2016.10 is the latest, no 2016.20 yet.

    ........... I've left the SRD files in the directory on the unit; I can still place the ASR/SRX files on the SD card though, right? That will still work?
    Yes it will.

    I still don't know if my unit is only having a problem reading the SD on startup 'cause that's where the maps are or what it is.

    You can put any mixed arrangement of the Map img, ASR/SRX, JCV & POI on card and/or unit, provided you observe proper placement of them. SRD files remain in unit's ASR folder as you've done Try a different SD if still having problems or reformat your present one. No need to open a separate thread at present, if it gets OT we'll spin some posts off later.

    Okay, thanks for the additional info...

    Yeah the problem with my unit (Kenwood DNX9980HD) is an odd one. I just don't get what's wrong with it. It can read maps on the SD card fine but it won't read them at boot time...about 70% of the time. Instead it pretends there is no SD card inserted at all and just has the [non-routable] basemap available and nothing from the card. I have to eject the card (which is a pain because you have to hold the eject button for several seconds to lower the screen) and re-insert it and it works instantly. Thereafter, everything is fine. But most of the times at startup it doesn't read the card, so if I don't do the card re-insertion, I can't get maps. It does sometimes load the card like it should but usually it doesn't. I don't even have to remove the card entirely just push it in so it pops out and push it in again and boom it works.

    I've tried clearing the non-vol, resetting the unit, all to no avail. I've also tried three different SD cards and all react the same. It all started when I upgraded from 2015.10 to 2015.40 maps. The 2015.10 worked absolutely fine off the SD card at all times, with no maps on the unit's internal flash. When I moved to 2015.40 on the same SD card I started having issues. The map would disappear mid-routing/mid-driving at times, leaving me with just the base and lost or frozen routing. So then I tried the same maps on two other SD cards and the same thing. So, naturally, I figured it was the maps so went back to 2015.10 thinking that should solve the issues. Well I don't lose maps at random any more (once the card is re-inserted after boot it works fine) but at boot it won't read the SD card...I've tried three different map version across three different SDs and it's always the same. It's extremely annoying and I have no idea why it's happening.

    The only solution I can think of is to put the maps on the internal flash but the problem is there just isn't enough space to fit the full NA map, plus 3D buildings, plus ASR, plus JCV. I don't think there's enough to put the "Can+US" mapset either as that's the bulk of the NA maps anyway and it's not much smaller I don't think. So I was thinking just make a custom mapset that's much smaller and fit everything but if ASR won't work that idea is out the window. Now I'm wondering if putting the main map .img on the unit will allow it to boot and read the SD card properly (where I could put all the other files) but I have to try and see what happens.

    Try spaying some Electrical Contact cleaner on the sd card terminals and immediately quickly inserting and ejecting it repeatedly. Do that a few times because it may be only that the internal contacts of the card reader are a bit dirty. You could spray a little into the reader opening itself before inserting/ejecting repeatedly but if you try that do not power up the unit until absolutely certain the cleaner has evaporated. Most dedicated cleaners are non-conductive but i'd be extremely cautious with it regardless. Use only genuine contact cleaner not anything like WD40 nor any other hydrocarbon liquids.

    I thought of this but I've come to the conclusion it's probably nothing to do with the slot and just a problem with the unit's f/w when it boots. Because if I look in the slot with a flashlight the contacts look clean and shiny. I was thinking maybe it's the physical card detection switch (as SD card uses this to detect the card--signal CD). But then this makes no sense either because if I try to move/wiggle the card in the slot without pushing it in, it does nothing. I mean the card doesn't really move much if you try that but still should be enough to get an intermittent switch.

    Also I can turn the unit OFF, wait for it to completely shut down and turn it ON again, and sometimes that's also enough for it to read the card--it's very random. This is with the vehicle completely stationary as well so nothing is moving around. I never lose the card while driving once it has been re-inserted after the unit has started either (something that would indicate a bad or dirty slot).

    I've come to the conclusion it is not the slot at all; I can give the contact cleaner a shot (pardon the pun) but I doubt it will do anything. Right now I'm trying with everything but the ASR on the unit and the ASR on the card (I'm using 2015.10 for the moment until I find the ASR files for 2016.10). I've only booted it a few times but SD card has come up each time (going into developer menu and file manager and seeing the SD card is not greyed out); however that was only a few boots...have to try for about a week of normal use and check everyday if the SD card is recognized before I can be sure.

    Seems an odd problem indeed. I've moved these post to Kenwood-Garmin section to get more targeted attention, maybe other Kenwood users have had this also [your bad pun pardoned for sure, is trumped by my 'contract' typo anyway ].

    Some Garmin PNAs will exhibit such behavour if a card is inserted when running, others will reboot automatically. Not reading the card on booting is unusual however.

    Okay thanks!

    Yeah it's definitely a weird problem especially when it never existed before. It should be noted that updating the Garmin firmware to 2.20 on this unit (the only update there is) is a bad mistake as well--it causes a the particularly bad issue of the dreaded RTL trap which can only be avoided by regularly clearing the shutdown causes else an RTL trap will occur when the non vol fills and freeze up the unit. However the SD card problem did not happen with that update as I updated the unit long before this started occurring. I really wish Garmin would update this firmware or for there to be a way for me to get the 2.10 firmware back but it seems impossible. Is there a link/email to submit errors in f/w to Garmin? Perhaps they could at least look into it--it's a well known and readily repeatable error.

    Anyway what used to happen without maps on the unit (and SD card maps inserted) was you'd get the message of "No maps found on unit...no routing...blah blah" at startup but it would disappear and the SD maps would load and be fully accessible. However for the last little while it's been a nightmare, refusing to read the card most of the time and requiring the re-insertion routine. I'm hoping I've now solved the problem but I gotta give it some time to see if it recurs, 'cause I really don't trust it anymore lol.

    Ahh interesting. Perhaps I will try that if my current strategy has failed. The good news is I can fit most of the files on the unit's available ~3.65GiB, just not all of them. As long as I keep the main IMG on the unit I think it will be okay but remains to be seen as mentioned above. Will report back in a few days (or if it fails to read again anytime soon).

    Runtime Liberty Trap crashes are a separate issue as you clearly understand and would be unrelated to your unit's SD read problem. I don't think the map img file naming is in fact an issue in this case because the SD isn't being acknowledge at all by the unit at times. Some older Garmin units with later software versions can indeed use both gmapsupp.img and gmapsup1.img in Garmin folder of SD however and it's worth trying the rename as suggested by our good friend ORAK. He is the resident Kenwood expert and you should follow any advice from him about an attempt of fw downgrade advisability.

    Unlike the direct system to report map errors, afaik they don't have a particular link for normal users to report any specific problems in released fw like with UAT versions. Just email support [and good luck with that!]. I've made a start for you below [just the easy bits ]:
