Navigation Problem, Please Help!

[fernandolpa]

My navigation system has lost the GPS signal. Now I have a red dash crossing the GPS signal on the screen and everything is white. Rest of nav menus are working properly except the one to change the country.

I had run the diagnostic menus and everything looks fine. Antenna is also ok, and tested.

I tried to change the GPS receptor module from the CPU but the $%&/&%% is solded, not like the OEM part that I bought, which has a connector (DENSO).

My CPU is an AISIN.

Any ideas besides going to Lexus dealer? They only tell me to replace the unit (Actually they looooove money).

Sorry but replacing the unit is not in my list...I live in an Island and GS is not necessary at all, but I would like to have it operational again.
