Important ! For bootloader 1.0100 and 1.0200 (or generally starting with 1. ) Please See this post first http://www.navitotal.com/forums/showthread.php?943-Bootloader-1.0100-and-1.0200&p=2279#post2279

I've tried to collect some of the latest bootloaders from all over the WWW.

This is only for information ,no links provided!!
The list is not complete but the most important bootloaders are there.
Here is a little list with things to know :
5.5012 - support for SD cards >2GB on TT ONE
5.5022 - bug fixed for writing over the 4GB barrier
5.5105 support for micro SDHC - only good for GOX40 models!!
5.5112 - full support for SDHC on all Tomtom models,also needed to use Navcore 8.412 and 8.410
5.5128 - needed for full support of Navcore 8.413(affects only ONE XL LIVE models-other will works with lower Navcore)
5.5130 - latest bootloader for the new 2009 models

Right now the 5.5022 seems to be the best to go because it is one of the fastest and supports the bigger SD cards.
5.5022 is the best choice for older models like the 300 and 500!
5.5105 is reported to work fine on 500 as well.
5.5105 can cause problems on ONE models!

For older models like Go 300,500 ,ONE V1 or classic I strongly recommend not to use bootloaders higher than 5.5022 - if you "brick" your GPS you can only hope to get it back to live with a higher bootloader that supports your system.
5.5128 can brick your old first model ONE,300 and 500 models!
Update only if you really have to!!

This list is not complete ,but maybe with some help it will be soon !
No bootloaders are provided here to download because of the risks stated above.
Please feel free to post more infos and know problems with the different bootloader versions as well as some feedback what bootloader works fine on older models.
I would like to know what bootloader is USB1.1 only and which ones support only USB2.0 .
