Hey guys,
Now I'm using TSST corp. SH-224DB ROM (burner). So far i had some successful burned disk which are working in some car models but in some cases disks are not readable due to i believe burning quality. Slowest burning DVD speed is 4x on mine ROM. Recommended burning speed on most of the navigation DVDs is 1x or slowest possible. 4x is ok in some cases but is not that good for burning ...
