Well, I ignored all the bad reports about Coocase and, seduced by a price of $143 US to my door in Canada (shipped from Sonic Moto in Italy, arrived in less than a week!!) I bought a S48 Astra case (the one with the remote and alarm) It looks good, went on my R1200RT without too much trouble, the wiring was straightforward and the lights and brake light work.
BUT the remote doesn't work and neither does the automatic locking or alarm. The battery in the remote is 12V (27A battery) but it was only showing 9.9, which may account for the remote. But why doesn't the automatic locking not work - I would have thought that was independent.
Any ideas, anyone?
