Hi folks,

I'm taking on a 1200 mile tour next spring (my first longer than a day's riding) and bought a Lezyene Super GPS to help with training and navigation. Annoyingly I've found out that I bought one of their first year models (it was 2nd hand) and it doesn't do navigation at all. Back to square one.

I'd still like turn by turn GPS for the trip, and the currently I'm training with heart rate. I wondered which of my options is the best bet, or if you have any other suggestions that I should consider?


. I could pick up something like a Wahoo Elemnt new. That would definitely do the mapping and heart rate data. Battery life is apparently good compared to Garmin alternatives, but it would take a serious chunk out of the trips budget. I'd have to compromise elsewhere to compensate.

.I could get a 2nd hand Garmin, but I'm unsure which models will fit my needs? 520 & 820 used are about the price of a new Wahoo.... 810? 510? I don't know.

.I can borrow a Garmin eTrex from a walker I know. That gets me mapping for free, but not HR. Given that's how I'm training, I'll end up using the Leyzene too. I'm not keen on having 2 devices on the bike, 2x the charging problems.

.I could use my phone, though I worry about having my only communication device doing the mapping too - if it runs flat I'll be in double trouble! Maybe I could pick up a used smartphone to double up as GPS?

I'd like it to pair with my Polar HR monitor and preferably upload to Strava without too much faff - the Leyzene is a bit fiddly and frequently unpairs with my phone.
Above all, I want unit I can rely on for navigation over a decent tour!

Any ideas?
