I prefer decimal degrees, that is the numbering system we were taught at school and its easy to explain to anyone with a basic maths background. We experience the very same problem, people are location illiterate and working with coordinates can be frustrating if not dangerous.  So many guide...

Looks like a Nuvi 500 with (maybe) different firmware and bike mount - if so, definitely a rip off.

As for the DEM downloads, you are correct, only 90m pixel data available for download at the moment, but this should be plenty to be able to generate up to 5m contours as their verticle resolution is pretty good. Yip, 90m is not bad at all, but you know what its like, you always want more -...

I have no problem with any critique on T4A, its the only way we will know how to evolve the maps - thats the way we have been doing it for 10 years and the map you see today is essentially designed by a forum of users and build by a stubborn old man who now only travel by bike, so a biker...

I do my Mapsource route planning using Topo (switching to DEM now and then to get visual overview) and Google Earth.  I have basically given up on T4A - I have 8.02 and just cross-check now and then.  It does point out interesting stuff, but I will never rely on T4A alone while on the road, just...

If you know where to download SRTM 30, kindly share the link.  As far as I know they are holding back on this data and only the 90m SRTM is available. Loaded scanned 1:50k onto Oregon yesterday.  You would have to do a lot of tweaking to get  more than 2 1:50k maps at a time on the unit. ...

{/quote] If the detail bothers you, I guess you can finetune what you see - haven't done that on Oregon yet as I like the detail but I know it is adjustable on Nuvi/Mobile XT functionality. As far as I know Nuvi only allows for Map detail to be set between Least and Most, same as Oregon...

dakardrix, I think you are confusing DEM with Topo & Rec.  The DEM is build from 200m contours which can hardly be of any use to anyone.  I live in Paarl and around me I have mountains 800m high - on the DEM (on Oregon), these only show a slightly darker shade.  No way you can use it for...

When you say DEM, you probably mean the shaded relief on the GPS = useless in my mind as it is not detailed enough.  Just a pretty picture but no practical value. When you say Topo, I take it you mean Garmap Topo & Rec.  Don't use it myself as it is too much detail for small GPS screen, but...

Wouter is on his way to Angola (visa permitting).  I see he is in Walvis at the moment and was complaining about the demons on the C14 between Solitaire and Walvis.  He will try to find a way through to Zambia from Luanda...  Should be an great RR.

The bike needs a good general service and addition to that I am told by staunch KTM rider that at around 30 000km its time to replace cam bearings, cables, wheel bearings and seals, grease everything with copperslip, chaim & sprocket. I also want to replace all rubber pipes and clamps. I know...

TomTom does not support T4A maps

I am looking for a reliable mechanic for some major work on KTM 640 in Cape Town area - any suggetsions?

I had one to play with yesterday and it seems to be a great unit. I liked the fact that it is a 'Nuvi' made to last on a bike (the Nuvi 500 seem to be robust enough and it looks as if similar technology was used). What I would like to confirm from existing users are the display of POI's on the...

I will ask Sarel Sam who compiles the legacy maps to post a proper technical explanation - Sarel might even be somewhere on this forum already? I used the normal T4A on 276c on West Coast trip with no issues, I think it only causes a clash when Garmap and T4A are loaded together on legacy...

used Oregon and 276 on recent trip.  Oregon is great unit but the USB connector is a PITA.  Even in my Disco it gives me issues and I use it on batteries only most of the time. 276 is still a better unit for offroad navigation - the Oregon score points as a very good data logger, extra memory...
