  • Calculation Mode Problems

    Didn't one of the recent map updates cause strange routing problems on certain Nuvi models?

    BTW, hard reset instructions are here if needed: http://forums.gpsreview.net/discussion/21511/x/p1/
  • Need Help With New Garmin RV 760LMT

    Custom avoidances are covered on page 7 of your manual: http://static.garmin.com/pumac/RV_760_OM_EN.pdf

    However, I don't think you quite understand their function. You can't create a global avoidance (avoiding all dead end streets), you must choose a specific street or area. For example, you could select the whole area around a city to avoid being routed through it.

    Global avoidances are found under Settings > Navigation > Avoidances

    I don't think you can specifically avoid dead end streets though. However, the unit (is supposedly) smart enough not to send you down a dead end street, unless that's where your destination is. :)

    No way to disable the warnings, thank Garmin's legal department for that, ;)

    The Dezl 760 hardware is the same as the RV760 (I have a Dezl 760), however the software (specificlaly the user interface) is completely different. The Dezl model was released in 2012 and has an interface similar to the 2012 Nuvi - almost identical to the Nuvi 3590 in fact. But the RV model was released in 2013 and has an interface more similar to the Nuvi 3597. The Dezl models are also slanted more towards commercial trucks and not recreational drivers.
  • Oregon 450 connected to PC - shows as one drive or two?

    Sometimes the the card doesn't make good contact in the carrier on the GPS. Make sure that it is properly seated and that the metal cover is slid down and latched in place. IIRC, the Oregon will show as two drives if the card slot is empty, but when you try to open the empty one, your computer will tell you to insert a card.
  • TRANSFERRING GMAPSUPP.IMG FILE TO MICRO SD CARD

    Is the file larger than 4gb? If so, it will not work because 4gb is the maximum allowable file size for the FAT32 filesystem that Garmin uses for their devices.

    Unfortunately, that is a problem for older GPS units like the 76csx (I have a 60csx, which is the same thing in a different case). Newer models allow multiple .img files, and they also have internal memory that can be used for maps. But you are limited to just one file named gmapsupp.img on the 76csx.

    Assuming that this is the problem, then about all you can do is select smaller portions of the topo and City Navigator maps, so that the file is less than 4gb.

    Also, when you say "US Topo", are you talking about the old version that was supplied on DVD and covers the entire US? Aside from the 4gb issue, you will not be able to load that entire map on your GPS due to another limitation of Garmin devices.

    Maps are broken down into smaller tiles called "segments". Your 76csx can only access approximately 2,000 of these segments but the entire US topo map consists of about 3,500 segments. So there is no way to load that entire map onto your GPS (well, you can "load" it, but it will not work properly). Again, the only solution is to choose a smaller portion of the map.

    And it is even worse, because the 2,000 segment limit is the total of ALL maps installed on your GPS, so you also have to consider how many segments the City Navigator map includes.

    Finally, I suggest that you use Mapsource instead of Basecamp/MapInstall. That is the software for which your 76csx was designed and I think it works better with these old devices. But it sounds like you are using a Mac and Mapsource is a Windows program. Do you have access to a PC that you could use for this instead? Or perhaps Parallels, etc on your Mac? You can download Mapsource here: http://www8.garmin.com/support/download_details.jsp?id=209

    One useful thing about Mapsource is that it will show you how many segments are included in the maps you have selected to send.
  • planing trip want to add addresses to my favorites before I get there

    The economics of this can be counterintuitive. ;) You might also consider buying a factory refurb Nuvi 2577, they have the same 12 month warranty as a new device. This model is pre-loaded with full US and EU maps and includes lifetime updates.

    Shop around for the best price, a quick search found them at GPSCity for $149. That's only $50 more than buying the full EU map for your 52LM and it also has more internal memory to hold both the US and EU maps. This would give you free lifetime updates for both the US and EU. If you buy a separate map of the EU, it cannot be updated.
