I've had my 235 for a few weeks now and really like it but a few times I find the GPS really slow to lock on. I don't use my 235 for anything other than running so turn it off in between runs. Today I turned it on 10mins before I went running (I live in a flat), I also waited outside for around 3minutes while I put my shoes on but nothing. The GPS tracking didn't kick in until around the 3km mark of outdoor road running (around 13mins). This is the 3rd time this has happened and just seems odd, my iPhone was generally very quick to pickup GPS signal. Also worth noting the date/time is wrong when I turn it on.
Anyone else experienced this?
