Problem SOLVED. I kept researching and discovered ipaq tools software to be able to open IGO default_skincol_landscape.bmp files. I also read where using an older WinRAR software will be more effective. I opened the data.zip from my igo software using WinRAR on my pc. Then I navigated to the 800x480 folder in data.zip. I dragged the file out to a new folder I created to edit these files. Then I opened it up with ipaq tools software, and saved it as a .png file. I then opened that png file in Microsoft paint. I resized it from 960x600 to 1024x600 and saved it as the resized png file. Then I navigated to that png with ipaq tools again, and saved it as IGO bmp file. After that, I just dragged it right back into the same zip folder I had open in data.zip/ui-android/800x480 folder. It replaced the original file with the one that was modified. I then took the entire data.zip and put on sd card, then inserted sd card into my device (my device takes 2 sd cards, so my gps software is on one, and the other I use to copy and edit files). When my head unit device booted, I went to IGO folder on gps sd card and changed the name of the original data.zip to data1.zip just in case I needed to use it again. Then copied my new data.zip into the IGO directory on my gps sd card. Booted it up and it worked perfectly. Now my background is full size like the rest of the app and I used the diMka 1.1.4 background. So I have the full theme (skin) and I am now able to use the right size background. Very happy as the IGO program looks and performs great now. Thanks to all of you for your help, especially Costas and Wojpen, and anyone else who chimed in. I learned a LOT figuring this out.
