My nuvi takes up to 3 minutes from a cold start. I can imagine some folk would think this is because of interference.
Also, in severe rain it will lose the satellites.

My Garmin NUVI 255WT works relatively well except when I place in the windshield of my new Toyota Highlander. The Highlander has a UV protective coating which seems to impede the aqusition of satellite signals and in some cases has caused the NUVI to get lost. Garmin does not offer an external antenna for this model. Can anyone suggest a current Garmin GPS that supports the addition of an external antenna?
