garmin won't recieve signal

Sometimes, when I use Garmin or another GPS application, the sattelite signal is slow to be found. I have to wait few minutes, like more than 5-10 minutes :/

You need the latest version, 5.00.10, for it to work with the i8510. Also, the program needs to be unlocked (payed for), for it to work with the internal GPS.

Don't forget to update the GPS+ once a week for a faster lock.

when i check the about thing on garmin it only says unlock esn now as befor it sed imei and somethin else

You need your IMEI to unlock it. But if it only displays that number, it's probably already unlocked. Try the other tips I gave. Do you get a lock with google maps?
