Any Garmin gurus????

I strongly suspect you will be fine, but if you call Garmin they will tell you. I still use a 188 and find it better suited for my needs than anything new out there. I had to change the memory battery in mine and spoke to Garmin's customer support team. They were very helpful right down to the part numbers for batteries etc I needed.

Nightfighter,

Looking on the Garmin sight both of those units use NMEA 0183 in/out port so looks like you my be good.

Numbskull, couldnt agree with you more. For my needs, I have a 172C and love it, last I tried I could still update the software. I like it much better than all their newer stuff. Also have a simple 152GPS that I also like but no you can't even update that software which I think is criminal BS.
