Thread: Transform a Nuvi 37xx in a Nuvi 34xx for dummies

@feroya
Best to do some extra reading of the thread before posting. e.g. the following is from [Only registered and activated users can see links. ]:

My Garmin doesn't know that you updated to 34xx. Mygarmin dashboard identifying your device by UnitID. Because UnitID is the same it identifies device as 3790.
Webupdater reads GarminDevice.xml and here info is changed. Know Webupdater identifies it as 3490.

P.S. If you have LMT for your 3790 you will get updates for "new" 3490. These updates will be as for 3490, not 3790. You'll get sid,asr and other files required for 3490.

How the speed limit displays is now confusing the heck out of me. In my 265W, 2350 and 13xx's it displays as square/rectangle (but in different place on map for 265W), but in 3790 it displays as circle. All with locale set to AU using the same map. In GMXT it displays as circle or square depending on the country map used (circle for older CNNTEU for instance, square for others). So go figure 'coz it's got me stumped. I always thought that the speed limit info display type was embedded in the map info, but maybe as you say the Locale setting also influences it. Certainly in my recent experience the device model does certainly. Is there a definitive answer: Locale, Map, Software, Unit/model, or a combination of them??

EDIT: OK, got it. Although the basic SLI info is embedded in the map, how it displays is dependent on both Locale setting AND the Model. E.G. 3xxx displays circle with EU or AU locate, but rectangle with US. Others (265W, 13xx, 2350, 40/50) display circle with EU locale and rectangle with US or AU. Garmin is so garmin..... n'est ce pas?
