Any Garmin gurus????

I love my 188c. i often think about getting bigger/badder/newer, but if it ain't broke, don't fix.

i bought a new wiring harness 2 years ago, and it seemed like it was universal. The antenna I am almost certain it is universal (to garmin of course). but like numbskull said, call garmin, i'm sure they will have the answer even though the 188c is no longer supported.

My antenna is not compatible. Would have to upgrade to a 17 or 19 antenna. Customer support was good. Thanks George. Hmm.......
