It's absolutely crazy the amount of control and options you have with some of this software.....

I've spent the last 48 hours or so reading as much as I can around this site (and the oregon wiki) and i'm really quite surprised garmin doesn't have a better manual for their products. 

Anyway....I do after looking into things have a few more questions...

My 450t obviously came pre-loaded with the 100k topo basemap and I also purchased the NA road SD card allowing me to use this for driving as well.  After looking through several tutorials I was going to try and upload a Yosemite Topo/Trail NP map onto my unit.  My plan was to use this detailed map of Yosemite to create a track for the backpacking trip I will be taking for my honeymoon in 2 months.  Once I selected the area of the map I want to load and I create my track I think its time to upload......the reason I haven't yet is....i've heard a lot of people warn to be careful when uploading to your unit to make sure you're not overwriting any information.....

So the short of the long here is once I select the map that i'm interested in and sketch the track over the map, once I hit send to device it gives me the choice of 450t which seems like the right choice.  I'm just concerned that i'll overwrite something I don't want to and mess up my navigation SD card or the 100k basemap..


This probably seems like a really simple question, I just don't want to mess anything up on my first upload....

Thank you in advance for the help, this site has a lot of great information

Hard to believe I actually had to follow the steps in order....wow....hopefully thats the dumbest question I ask on the forum...

Thanks for your help!

Hi All,

I've spent the last couple days familiarizing myself with the unit and feel like I have a pretty good feel for the basic uses....

After looking around on the internet for awhile I was excited to try and use Mapsource for this GPS.  I was also a little surprised to find that Mapsource didn't come with the unit.  Figuring it was a free download I can't seem to find it anywhere, is there something i'm missing?

I looked under the tutorials and saw the link for downloading mapsource, but that will only seem to take me to the update...when I download that it recognizes that I don't currently have the software and it then kicks me off...

It came preloaded with the 100k basemap and I also purchased the NA SD card for driving purposes....please tell me I don't need to spend another 100 bucks to be able to download the software?

Sorry for the long post but thanks in advance for any and all help,

Travis
