My Rider 1 is hard wired to my 1200GS and soon started switching itself off and on, owing to the rubber top mount flexing and allowing the contacts to part (on-road use only!), so I fitted the Wunderlich alloy bracket kit which reinforces the original mount rather than replacing it. Success, and cheaper then the Touratech item, lovely though it is!
Nippy Norman's, part no. WUN-8600880, £39. Locks it on to the mount too.
However my TTR1 goes on strike occasionally, just dead, won't switch on. Chuck it in the drawer, get it out a few days later, works perfectly! Anyone else had this?
I liked the Tom Tom until I bought a Garmin Zumo 550. Much better, plus superb bracket with proper RAM mounts. Did 2000 miles through Belgium and Germany in the summer no problem, and all round the Moroccan pistes last January in my 4x4 camper truck - 'cos it tracks you off-road too - with the (supplied) car windscreen bracket with built-in speaker. Prices have tumbled since last year so it's comparable with the Rider 2.
