Runs pretty fast. The link to phone and headset is convenient. Don't seem to have a problem with running down my phone battery as many others have experienced. Main comparison is to the China brand running a Windows application. Used Igo on that and was pleased with their guidance application as far as screen information and overall guidance....it actually used TomTom maps. I prefer the Igo over the TomTom but this device is pretty seamless. Would recommend this to a potential buyer for their motorcycle application
Rider 550 received recently. Controls seem intuitive. Screen touch is quite sensitive (can adjust sensitivity, but I had it on ‘no gloves‘ setting & barely touch screen to have characters populate). Screen could be much brighter in daytime - think I will have to get a sun shade accessory for it. Haven’t used it at night yet. Re accessories- be aware the Rider550 does NOT have a MINI port...So the car or wall charger additional accessory offered that has a MINI plug isn’t going to plug in to this unit. It has a MICRO port. Also has an SD card slot; haven’t used that yet.
