I have a Garmin 182 GPS with internal antena.
I am switching the GPS from a boat with no cover to a boat with a hard T top.
Will the GPS continue to work?
If not, is there an adapter I can purchase?
Please share your thoughts.

my bet is you'll have no problem, just a bit slower to acquire...

This subject has been discussed before on the forum and the concensus was it will work but slower to lockin. I have a 176c that worked ok on the internal antenna but much faster when I added a external antenna. I had problems seeing the screen on the 176c, so when the prices dropped on the 182 I got one. I mounted the 182 behind the 176c and used the ext antenna on the 182. With the 176c on internal antenna mounted in front of the 182 it would not lock in. The 182 can be converted from internal to external, but I do not remember the details. Some one on this forum contacted Garmin for the details.

GanderVA,
Thanks for the info.
I called Garmin today and learned that the 182 will accept an external antena.
It involves the replacement of the back cover with a replacement cover (approx $14.00), together with adding a remote antena.

It took my older Garmin 152 about 3 minutes to reaquire the signals when I moved the boat from Georgia to western Mexico on the trailer.
After that, my cheaper Garmin with the internal antenna now aquires in less than 15 seconds, mounted on the dash with a TTOP and electronics box.
The fish finder sits on the same console dash to left of it, and the counsol step up is on the right, so the only clear view is forwards and back.
I would leave yours as it is as it will work just fine, and this way you do not have to worry about waterproffing after replacing the back cover either.

Don't worry about it. Very likely you'll be fine and will have a good GPS lock after you add the roof.
