I'm in the market for a new cycling computer so thought I'd ask on here for opinions (good or bad) on the following.... My main interest is navigation. I'm not particularly bothered about cadence sensors, power outputs etc and so I've come across the following.... Garmin Edge 530 Can anyone guarantee that maps created with mkgmap currently work on this device. I discovered the mkgmap project when looking for a source of free maps for Garmin devices as I think the policy of Garmin to charge extra for maps on a GPS is insulting. https://www.garmin.com/en-GB/p/621224 Hammerhead Karoo 2 Pricier option but is well reviewed. I'm guessing proprietary maps but it claims bi-monthly updates https://www.uk.hammerhead.io/products/hammerhead-karoo-2 Mio Cyclo 215 Cheapest but I've never heard of them and so I'm wary https://www.mio.com/en_gb/products/outdoors/cycling-navigation/cyclo-200-ser... I've already ruled out Wahoo but if anyone has any other alternatives or comments I'm willing to listen Thanks for reading and for any replies
