In my case, I used a Memorex DVD+R DL and it finally worked in my car. I've tried using all sorts of single layer DVDs with no luck. Even though the images easily fit onto a single layer disc the nav system seems to require DL discs. This may not be so for all cars, but it is for mine. I'm also willing to bet that this may get discs working on other nav/car models as well. Hope this helps. I'd be interested in knowing if it worked for others.
Anyway, I used imgburn to burn the image and two prompts appear when using a dual layer disc after clicking burn. For the first prompt click yes, click no for the second prompt. Basically this tells imgburn to go ahead and burn on a DL disc even though the image fits on a single layer disc. It also tells imgburn to spread the image over both layers of the DL disc even though it fits on one layer.
If you need help with this PM me.
I've created so many copies that never worked properly I had begun to give up. I've tried different brands, DVD+R, DVD-R all with fleeting or no success. The DUAL LAYERED disc is the only thing that worked for me. If anyone is having trouble please try this before you give up. Thanks again!
