Well for anyone else in Europe trying to get on the homelink wagon by getting a US mirror don't bother, homelink has confirmed the frequencies are lame:
I am afraid, that if your Homelink system is a US version, it hence uses radio frequencies which are different from the EU versions.
Some of these frequencies are reserved for special purposes such as police radio, emergency services, public authorities, etc. Therefore, it is not permitted to use the US frequencies in Europe and the other way round, making it impossible to operate an EU garage door opener with a US Homelink System
