Hi
Sure you can use an external antenna.
Here it is
It is however really only useful to allow for decent veiw of satelites when the unit is monuted under a the signal shadow of a cabin or below decks. Any GPS will not perform as well if a decent shot of 3 or more satleites is not acheived. I suspect this is what is hampering your device. Using the external antenna mounted to get maximum view of the sky will eliminate any such issues for you.
Please take a moment to rate this solution. heers

My Garman gps map 498 turns on but stays to dark to read or see.


It's probably the ccfl is burned out. The illuminator is a very interesting (and very thin) little contraption. Inside the illuminator is an L-shaped ccfl (cold cathode fluresent lamp.) They run at very high voltages. Eventually the ccfl burns out.
Go to www.ccflwarehouse.com. They can fix you up with a mail-in replacement for around $35.
