How to install a downloaded Bluechart map on a 620 plotter?

fantomet11 · 31st March 2012, 09:38 AM

I've bought a new 620 gps and downloaded a map (.img). I've read on this forum for hours searching for a way to get this map installed on the gps, but but I'm still confused.
What i have done:
- downloaded the map (gmappsupp.img)
- run the Garmin unlock generator, and created a gmapsupp.unl file
- run the Fast IMG unlocker (it created a garmindevice.XML file)
- cpoied these files (img, unl, xml) to a SD card an put this into the gps
Still the gps finds no maps.....

I've also downloaded Mapsource, but I'm not sure if this program can help me. Mapsource also cannot find any maps on the SD-card.

Appriciate any tips.

Copy the unlocked map in a Garmin folder in an sd , renaming the .img to gmapsupp.img, if it's unlocked dont add the.unl file or gps wont see it.
Mapsource doesnt display Bluecharts, you need Homeport.
The Garmindevice.XML hasnt been created by the unlocker but by your device itself. Dont run unlockers directly in the devices, but run them on pc.

Everything is done as described below. I get message in boating mode: "Can't Authenticate Maps" In drive mode everything is ok, unlocker has generated good key.
620 Software 3.70, Supplement map VEU713-Finland V2012.2 v13.52. Thank you in advance for good advice!
