    Conecting Garmin Nuvi 2455LT to the PC and loading maps problem!

    I recently bought Garmin Nuvi 2455LT. When I try to connect to the PC, some MTE player starts (on Windows XP SP3 Pro) and device is not recognized on PC (don't appear in My computer), MapSource software can't find it as device.

    When I connect the Nuvi 2455LT on PC's with Windows XP SP3 Home Edition and Windows 7 SP1 Home Premium, computers recognize the device as Nuvi 2455 under 'My Computer" but Nuvi device didn't get the letter as other devices in the computer "C, D, E... etc". MapSource can't find the connected device and I can't upload maps into the 2455LT or into memory card that is inserted in the device (in the computer appear without letter)

    need some help

    Thank you

    Choose from the service menu on the speedometer Mass Storage Mode.

    Tnx for the advice.. I can't find that option

    Can you tell me please, more precisely how to switch to Mass Storage mode?

    (When I plug the Nuvi 2455LT to the computer, on it's screen is shown only 'Garmin" logo and a picture that shows that is connected to the PC (touch screen not responding that time and I can't power on the device))

    Got to this menu:

    Press the Speedometer for 6 seconds 300x174

    Hold the speedometer for 30 sec. Then MTP Settings -> Mass Storage

    I just tried to load Europe City Navigator 2012.20 unlocked with Fast Img Unlocker 2.1 and map in not shown in the device (like its never loaded). tried to unlock the map with jetmouse keygen (latest), nuvi reports that "can't autenticate maps"...

    any suggestion, please?

    Sorry, I don't know. I think you should better use SD card. As it is safer.

    I put the unlocked map on microSD card.. tried that same microSD card on nuvi 3760 and it works...

    I guess that this model got some new protection or it's limited with the file size (europe 2012.20 image file was around 2.3GB) which had no common sense (2455LM is newest model and today maps go way above 2GB in size)

    Put in SD/"Map" folder, anyname.img.
    If unlocked with FIU will work
