HWID 1582 it's a different device firmware, don't try to flash it in your nuvi or you'll brick it probably.

Sorry, I hadn't seen your reply here yet.
I'll try with nuvi2xx7and2xx8_530.rar then, this time with Webupdater, and not with Garmin Express :-)

i find nuvi 2xx7 and 2xx8 software version 4.60, but I don't know wether is for HWID 2077 or HWID 1582. Actually, I don't even know if it makes a difference, anyone can let me know?

(My Nüvi is the 2597 (HWID 2077), by the way, with the latest firmware (7.6). I want to roll it back to 4.60 to see if I can install a topo map from Mapsource.)

Here you are for HWID 2077:

Spoiler: 4.60

Thanks #Giomen!

It works, I have finally managed to roll down the firmware to 4.60. But...

Unfortunately my device (Nuvi 2597) really does not allow for other maps than the one from Lifetime update, through Garmin Express...

Hi,
I searched the forum for a hint to get the HWID of my nüvi 2598 LMT, I didn't find one. Can anyone help me, please?
Thank you!

From main screen ['Where To?/View Map' page] press and hold the battery symbol in upper RH corner for ~6 seconds to enter hidden menu > press either 'next' or 'back' repeatedly to reach 'Version Information' page > Start Test > More and look at first line: Boot BLK Bxxxx-00 etc. The four numbers 'xxxx' represent your HWID. Alternatively, look in a backup or connect unit in MSM to PC. Browse to Garmin root folder, look for GarminDevice.xml, open it with a web browser or text reader and search for '<PartNumber>006-Bxxxx-00</PartNumber>' near beginning of file.

GPS firmware 5.08
So this device can no longer use any unlocked map right?

I have a built in U.S. map and I wanted to have EU map with it, is buying the map online the only way to make it work?
:mn: Moved to existing thread

Firmware version of 7.40 indicates it's maybe a C4 unit with HWID2077 and if so you're out of luck. Please read [Only registered and activated users can see links. Click Here To Register...] in gimgunlock thread, in particular:

If you have 2xx7 (8) (PartNumber> 006-B1582-00), works
If you have 2xx7 (8) (PartNumber> 006-B2077-00), doesn't work.

Note: V7.40 is no longer in the changelog for C4 firmware, so it would seem it was not issued or if it was issued it was dropped [progression was V7.30 to V7.50]:

Some fw versions are solely 'OEM', i.e. factory loaded only to new units but never issued publicly. Please look at your unit's .System folder, if it has GUPDATE.GCD file in it please backup the file before updating the unit and please advise us here.
