All good advice generally and totally correct. Same 'model' but screens and even pcb can be different. I have an open 260 before me at the moment with a screen i've never seen before and with totally different connections to the mo.

As far as i know though, 37xx range all have the same. The difference in price doesn't mean a different product and the 3 examples in post #1 (even with $20 price variation from same supplier), and in the ebay link from Caty's post, are probably exactly the same product. The images appear identical, but the only way to be sure is to do as Caty said and check with Garmin, or do as TC111 said, take it out and check it first against what you are buying.
