Hi Chris,

The LXNAV GPS antenna with SMC connector for LX80x0 and LX90x0 products works great with Cambridge 302 units. I have tested them together.

I have them in stock for $55. Shipping from Minnesota to you in the UK would be about $30 using U.S. Postal Service 1st Class International Airmail.

Best Regards,

Paul Remde

Does anyone know the specification for the GPS connection for the Cambridge

Thanks
