As been said before- some HD micro sd cards do not work in the 60csx
I have sold mine and have 'de-registered' it from 'My Garmin' through the garmin website- This allows another owner to register the unit in their name. Ask the previous owner to de-register it.
If the maps on the unit are current (less than one year - Garmin used to offer a once only free update) and IF the previous owner has not doen so, then not registering it will loose you this update.
IF the previous owner has already doen this, you loose nothing on functionality. Garmin will always offer free operating software updates for the unit itself until it is discontinued. I am guessing the 60csx is out of warranty.
Garmin do offer a repair service for a fixed price.
As far as the what is on the sd card- you'll need a card reader (cheap as chips these days) to find out what is on there.
Your choices in the meantime are:
- ensure the unit is as up to date possible as far as its operating software is concerned (free from Garmin)
- Get a new sd blank sd card for your unit
- load OSM maps on it which are free
The 60csx works perfectly well without maps- not too useful for referencing but it will work on a straight line navigation basis - i.e between points of interest you create or may already have.
If you speak to Garmin and explain the map problem, they might agree depending on its age etc for you to send the original micro sd card back to them for unlocking.
If they say 'no' then you might have to buy City Nav Europe from them as a 'one off' purchase then pay another ( I think about £80) for free map updates for lifetime of the unit- if the unit dies, bang goes lifetime update!
hope this helps
