What are you running for a GPS on your ride?
What are the best features/why did you buy that model?
What do you dislike about it now that you have used it?
What did you pay for it?
How did you mount/wire it?
Doing it all over again, would you make a different choice?
My experience was with naitram's Garmin Quest. I borrowed it a few times and liked the portability of it (20hr battery powered). The only down side was that it didn't hold the entire country.
Enter the Garmin Quest2. All the benefits of the original but with more memory. It will hold all of North America.
So I bought it.

I despise this unit. Oh they added more memory, but didn't upgrade the processor. It takes forever to calculate a route and if you miss a turn, you might as well pull over and let it catch up or you will be in recalculation hell.
I contacted Garmin's support via email and went back and forth a few times until I said "so it isn't broke, it just sucks"
No further contact from them....go figure.
I tried to dump it on ebay for 100 less than I paid for it the previous month. No luck. I have kept it for almost a year now. I will do my homework this time around, hence this topic.
I welcome your response and candor as I want my next GPS to eliminate stress instead of adding to it.
