,, A mine of information, and collectively you've really helped me. I'm the complete opposite of a nerd. On this forum there are clearly some very capable people re tech. I'll take Karla advice and get a dedicated unit. I'm "reviewed out". Looks as though Garmin 530 offers a lot for£230.its not even the money. It's the user friendliness. I can't help but think if phones were the solution, Garmin, Lezyne, Wahoo et Al. would be out of business. My son uses his phone to navigate from London to North Herts and its all seamless to him. I bought a Garmin Touring in 2013, cycled to London via River Lea towpath. On way back I went more direct route through Barnet and used compass just headed approximately north, not that I was lost. At risk of repeating myself, all the performance data I don't need. I'm really hoping to do LEL next year and didn't want to rely on others. I have followed similar thread on yacf re phones and navigation and was baffled.
Many thanks, hopefully I'll catch up on the road.
