Syrius Snooper SATNAV

[lampgb]

Has anyone out there had any problems with this system? I bought one awhile back and have had nothing but trouble with mine. Often as not it will not find satallites. When it does fire up it will often drop out and in some cases switch itself off. Another disgruntled user has told me that there may a chip problem but that replacements are also a problem. I have emailed the product supplier twice but as yet they have not been courteous enough to reply. Any ideas please.
