for those interested there is a way to change the start up logo on both the new and old unit.
parameters, the image must be 800x480 resolution/24 bit color/sized to fit the 4x2 inch screen/must be in bmp format(bitmap)
you can use ANY immage as long as it is adjusted to meet the parameteres. even a familey photo.
something to consider, the unit only has 128mb of ram minus the OS and the factory logs. so do not go changing the logo every week, it will fill up fast. find the one you like and stick with it.
you can use an immage editor like photoshop, i used a freeware image editor called GIMP, to adjust the resolution and resize the image. IMPORTANT: your computer screen will automatically resize whatever you are working on to fit your computer screen. DO NOT USE THIS SIZE. adjust the pixels so what you actually see on your computer in front of you is no larger than 4 inches wide or 2 inches tall. if you save the immage the computer adjusted to fit your screen it will be too big to load on the unit and cause a load error. ask me how i know........
after you have your image load it to the root of an empty sd card. rename the immage to "logo.bmp"
start the unit. reset the unit with the reset button. put the sd card with the immage in the GPS card slot. USE THE REMOTE to start the update process by holding down the start button for 6 seconds or so untill you see it updating. you will see the image show up on the screen when it is updating. after the unit starts reset the unit and remove the sd card with the immage. start normally and it should be there.
if the image is too big it will cause a load error you will need firmwear to fix. same if the immage is in the wrong format, wrong resolution, wrong color bit.
i have firmwear they sent me to fix the problem with the clock reverting to china time when you use the GPS. this is how i figured out what NOT to do. lol.
i can e-mail the firmwear to you or you can complain about the clock problem and get it from the place you bought it. the problem with the firmwear they sent me is it is for the old unit. it will work on the new unit but you WILL LOSE the new radio UI. it will revert back to the old radio UI. but it will work.
so there is some risk involved. if you are not comfortable running updates and firmwear or do not hate the ram logo enough to risk loosing the radio UI do not do this. i have done it sucessfully on both the old and new unit. the only casualty is the new unit now has the old units UI. in expereimenting with this based on information i found on xda developers and gps forums i have had to run the firmwear countless times till i got it right. follow the parameters exactly and you will have no problems.
if i were you i would get the firmwear from the supplier before i started playing with it.
enjoy
