Check your HWID. If it's 1091, then there is currently no hack available.

Help- I was hoping if someone could help me.
I do not know what board I have.
I have gone into the diagnostic mode by pressing the battery icon but all I see on the top is:
SW 4.50 nuvi 205w TP P1 V6 2GB

This unit was purchased in November of 2008, so if someone could help me find out what board I have it would be appreciated. I'm trying to figure out if I could update this or not, is there another way to check?

fyi I have yet to update anything on this unit I installed the garmin dashboard from my computer but did not really update anything yet.

Thanks in advance.

I followed the directions and at Step 2 #10, the Garmin drive doesn't show up in my computer and the unit says "System Files Missing." It also will not turn off. It has an S3 board with firmware 5.40.

Hi,

I followed the guide but with a few changes. I have a nuvi 255W s3. I tried to enter to preboot mode but I neber made it. When I was entering diagnostic mode with the battery icon I could do all the updates mentioned in the guide. I followed the steps and finally I had a sg/my firmware in my unit. I checked and the lane assist was working. However the unit made mistakes in the calculations. For example I had 500m to a turn and I could hear "3 miles turn right" and so on. So I desided to revert to the old one.

I went into diagnostic mode and used a different update file. I t updated ok and I run the garmin updater to do a final restoration of every file. After that the unit stuck in the loader/ loading screen and since I can't get into preboot mode I can't do anything.

Is there a way to unbrick the unit?

UPDATE : Too late. I sold it for parts!

Followed the instructions and "WOW" it worked like a charm.

I further upgraded the firmware from 2.7 to 3.0 with no loss of function.

In fact, V3.0 allows GPS tagged photos to be linked to any maps you have installed.
(I took the GPS Photos with my phone, and uploaded to Nuvi, in case you are wondering).
